Look at the diagram. Which angle is complementary to < EOD
A. < EOD
B. < EOC
C. < AOC
D. < AOB
Answers
< EOD + < AOB = 90
60 + 30 = 90
ur answer is < AOB
Answer:
D. [tex]\angle AOB[/tex]
Step-by-step explanation:
Since we know that complementary angles add up-to 90 degrees.
We can see from our given diagram that angle EOA and angle EOC is a linear pair of angles. The measure of angle EOA is 90 degrees, so EOC will be 90 degrees as well (Linear pair of angles must add up to 180 degrees).
We can also see that [tex]\angle EOC=\angle EOD+\angle COD[/tex].
Upon substituting value of angle EOC we will get,
[tex]90^o=\angle EOD+\angle COD[/tex]
We can see from our given diagram that angle COD and angle AOB are vertical angles.
[tex]\angle COD=\angle AOB[/tex]
Since vertical angles are equal, so by substitution property of equality we will get,
[tex]90^o=\angle EOD+\angle AOB[/tex]
Therefore, [tex]\angle AOB[/tex] is complementary to [tex]\angle EOD[/tex] and option D is the correct choice.

After finishing his shift, a security guard wrote 6.75 under "hours worked" on his time card. how long did he work ?
Answers
The security guard worked for 6 hours and 45 minutes, this is because 0.75 of an hour is equivalent to 45 minutes.
Explanation:In the context of this question, the security guard logged 6.75 hours on his shift. This figure is given in decimal format. To convert this into hours and minutes, you need to understand that .75 of an hour is three quarters of 60 minutes. So, 0.75 x 60 minutes is 45 minutes. Therefore, the security guard worked for 6 hours and 45 minutes.
This is equivalent to 6 hours and 45 minutes. In decimal form, 0.75 represents three-quarters of an hour, which is 45 minutes. So, he worked for 6 hours and 45 minutes.

The stage manager of a school play creates a rectangular acting area of 42 square yards. String lights will outline the acting area. To the nearest whole number, how many yards of string lights does the manager need to enclose this area?
omgggg please help guys
Answers
The number of yards of string lights the manager needs to enclose in this area is 26 yards.
Given that the stage manager of a school play creates a rectangular acting area of 42 square yards.
What is the perimeter of the rectangle?The perimeter of a rectangle is the total distance of its outer boundary. It is twice the sum of its length and width and it is calculated with the help of the formula: Perimeter = 2(length + width).
The number of yards of string lights that the manager needs to enclose the area is given by the perimeter of the rectangular area.
Let the length of the rectangular acting area be x, then the width is given by 42 / x.
Recall that the perimeter of a rectangle is given by
P = 2(length + width) = 2(x + 42/x) = 2x + 84/x
The perimeter is minimum when the differentiation of 2x + 84/x is equal to 0.
2-84/x² = 0
⇒2x²-84=0
⇒2x²=84
⇒x²=42
⇒x=√42
⇒x=6.48≈6.5
Now, perimeter = 2(6.5) + 84/6.5
=13+12.92
=25.92≈26
Therefore, the number of yards of string lights the manager needs to enclose in this area is 26 yards.

The numbers that should be multiplied to obtain 175² - 124² are 51 and 299. This is due to the algebraic concept of a difference of squares.
Explanation:The mathematical expression 175² - 124² can be represented as the difference of squares. The difference of squares is a special case in algebra where a² - b² can be factored into (a + b)(a - b). So, in this case, we can represent 175² - 124² as (175 + 124)(175 - 124).

Since the Mitchell family is renting a boat for the day, and the boat rental has a flat fee of $ 100 plus $ 20 for each hour, and they have to pay for a whole hour even if they are not out on the lake for a whole hour, to determine, if they want to spend $ 250 or less on the boat rental for the day, how many hours can they rent the boat, the following calculation must be performed:
Fixed cost + Variable cost multiplied by the number of hours = Final cost 100 + 20X = 250 20X = 150 X = 150/20 X = 7.5 100 + 20 x 8 = 100 + 160 = 260 100 + 20 x 7 = 100 + 140 = 240

The length of AM is 21.
Given that,
Point M should be the midpoint of the AB.AM = 3x + 3.AB = 8x - 6.Now
We can say that

Answer:
The correct answer is one point.
Step-by-step explanation:
In geometry, if two lines cross each other, they will do so at an exact point.
Imagine that the lines are formed by thousands of points located next to each other, which makes us see a line, therefore if they cross, they will do so at a single point that will have a coordinate in (x, y) format.
When the two lines are on the same plane, the following situations may occur:
if they match they have an unlimited number of points in common if they are different but they have the same slope they are parallel and they do not have points in common if the above does not happen, they have a single point of intersection.A patio floor is shaped like a rectangle with a

The length of each side of a square is 3 in. more than the length of each side of a smaller square. the sum of the areas of the squares is 269 in squared . in2. find the lengths of the sides of the two squares.
Answers
The length of the side of the big square is 13 in. while that of the smaller square is 10 in.
Square
Square is a quadrilateral in which all the sides are equal to each other. Also opposite sides are parallel to each other and all angles measure 90 degrees.
Let a represent the length of the bigger square side and b represent the length of each side of the smaller square, hence:
a = b + 3 (1)
Also:
a² + b² = 269
(b + 3)² + b² = 269
2b² + 6b - 260 = 0
b = -13 or 10. Since b cannot be negative hence b = 10.
a = b + 3 = 10 + 3 = 13

To find the lengths of the sides of the two squares with a combined area of 269 square inches, where the larger square has sides 3 inches longer than the smaller square, we set up a quadratic equation based on the areas. Solving the equation gives us 10 inches for the smaller square and 13 inches for the larger square.
Explanation:Finding the Lengths of the Sides of the Two Squares
We are given that the larger square has sides that are 3 inches longer than the sides of the smaller square and that the sum of their areas is 269 square inches. Let's denote the side length of the smaller square as s inches. Then, the side length of the larger square is (s + 3) inches.
The area of the smaller square is s^2, and the area of the larger square is (s + 3)^2. The sum of their areas is given by:
s^2 + (s + 3)^2 = 269
Expanding the equation gives us:
s^2 + s^2 + 6s + 9 = 269
Combining like terms, we get:
s^2 + s^2 + 6s + 9 - 269 = 0
2s^2 + 6s - 260 = 0
Dividing the entire equation by 2, we simplify to:
s^2 + 3s - 130 = 0
This is a quadratic equation that can be factored:
(s + 13)(s - 10) = 0
Setting each factor equal to zero gives us two possible solutions for s:
s + 13 = 0s - 10 = 0The negative solution is not physically meaningful for the length of a side, so we discard s = -13 and take s = 10 inches as the side length of the smaller square. The larger square, therefore, has sides of 13 inches.
So, the side lengths of the two squares are 10 inches and 13 inches respectively.

This diagram of airport runway intersections shows two parallel runways. A taxi way crosses both runways. How are 6 and 2 related?
a)corresponding angles
b) alternate interior angles
c)same side interior angles
d) none of these
Answers
Answer: a)corresponding angles
Step-by-step explanation:
When two lines are intersected by a transversal line then the non adjacent angles in the matching corners are known as pair of Corresponding Angles.In the given figure angle 6 and angle 2 are the two non adjacent angles in the matching corners , which we called as a pair of Corresponding Angles. {By definition}
Therefore, angle 2 and angle are related by corresponding angles .
In the given diagram, angles 6 and 2 are corresponding angles.
To determine how 6 and 2 are related, we will define each of the terms in the option.
Corresponding angles are formed where a line known as an intersecting transversal, crosses through a pair of straight lines. They are found at different intersections but on the same side of each parallel line and the same side of the transversal line.Alternate interior angles are angles formed when two parallel or non-parallel lines are intersected by a transversal. The angles are positioned at the inner corners of the intersections and lie on opposite sides of the transversal.Same side interior angles are two angles that are on the interior of two lines and specifically on the same side of the transversal
Angles 6 and 2 are found at different intersections but on the same side of the parallel lines and the same side of the transversal line.
Hence, angles 6 and 2 are corresponding angles.
