what are the lengths of the legs of a right triangle in which one acute angle measures 19° and the hypotensue is 15 units long?
Answers
Given:
m∠A = 19°
c = 15
By definition,
sin A = a/c
Therefore
a = c*sin A = 15*sin(19°) = 4.8835
cos A = b/c
Therefore
b = c*cos A = 15*cos(19°) =14.1828
Answer:
The lengths are 4.88, 14.18, and 15.00 (nearest hundredth)
Answer:
For plato users the correct option is D.

Rewrite the expression as a polynomial in standard form.
Answers
and then rewrite putting the number with the highest exponent first, the second highest and so on
The expression (2x² - x³ - 9x + 1) - (x³ + 7x - 3x² + 1) can be rewritten in standard form as -2x³ + 5x² - 16x
How did we get the value?To rewrite the expression (2x² - x³ - 9x + 1) - (x³ + 7x - 3x² + 1) as a polynomial in standard form, we can combine like terms.
First, let's distribute the negative sign in front of the parentheses:
(2x² - x³ - 9x + 1) - x³ - 7x + 3x² - 1
Next, let's group the like terms together:
2x² + 3x² - x³ - x³ - 9x - 7x + 1 - 1
Now, let's combine the terms:
(2x² + 3x²) + (-x³ - x³) + (-9x - 7x) + (1 - 1)
5x² - 2x³ - 16x + 0
Finally, the expression (2x² - x³ - 9x + 1) - (x³ + 7x - 3x² + 1) can be rewritten in standard form as:
-2x³ + 5x² - 16x

5+5x=-2x+5
Isolate the x. Add 2x to both sides, and subtract 5 from both sides
5 (-5) + 5x (+2x) = -2x (+2x) + 5 (-5)
5x + 2x = 5 - 5

Kristin is 20 miles behind a truck that is driving 50 miles per hour. How long will it take her to catch up to the truck? How far will she go in that time
Answers
It will take Kristin 24 minutes to catch up to the truck. She will travel a distance of 20 miles in that time.
Explanation:To calculate how long it will take for Kristin to catch up to the truck, we can use the equation: time = distance / speed. Since Kristin is 20 miles behind the truck, she will need to cover a distance of 20 miles to catch up to the truck. Assuming she drives at a constant speed, we can use her speed as the truck's speed since she needs to match it to catch up.
Time to catch up = 20 miles / 50 miles per hour = 0.4 hours = 24 minutes.
In that time, Kristin will travel the same distance as the truck. So, she will go 20 miles in 24 minutes.

An isosceles triangle has two sides of equal length. The third side is 5 less than twice the length of one of the other sides. If the perimeter of the triangle is 23 cm, what is the length of the third side? Explain how you would define a variable for this problem.
Answers
4x=28
x=7
2×7-5=9
The third side is 9 the variable is x
To find the length of the third side, we can set up an equation using variables. Solving the equation will give us the length of the third side.
Explanation:To solve this problem, we can define variables to represent the lengths of the two equal sides of the isosceles triangle. Let's say the length of each equal side is x. The third side can then be represented as 2x - 5. Since the perimeter of the triangle is 23 cm, we can set up an equation:
x + x + (2x - 5) = 23
Now we can solve for x:
4x - 5 = 23
4x = 28
x = 7
Therefore, the length of the third side is 2(7) - 5 = 9 cm.

Hope I helped :)
The sum of the angle measures of a polygon with 9 sides is 1260.
What is Angle Sum property?To find the sum of interior angles of a polygon, multiply the number of triangles in the polygon by 180°. The formula for calculating the sum of interior angles is ( n − 2 ) × 180 ∘ where is the number of sides. All the interior angles in a regular polygon are equal.
As, the sum of the interior angles
(x - 2) x 180 where x is number of sides.
Here, the angle sum for n side is 1260.
So, (n -2) 180 = 1260
n -2 = 1260 / 180
n - 2 = 7
n= 7+2
n= 9 sides
Thus, the polygon have 9 sides.

A 14.5-gallon gasoline tank is 3 — 4 full. how many gallons will it take to fi ll the tank?
Answers
It would take 3.625 gallons of gasoline to fill a 14.5-gallon tank that is already 3/4 full.
Explanation:The question asks how many gallons of gasoline are needed to fill a 14.5-gallon tank that is already 3/4 full. To find the amount needed to fill the tank, we first determine how much gasoline is currently in the tank by multiplying 14.5 gallons by 3/4:
14.5 gallons × 3/4 = 10.875 gallons
This means that there are 10.875 gallons of gasoline in the tank at the moment. To find out how much more gasoline is needed to fill the tank, we subtract this amount from the tank's total capacity:
14.5 gallons - 10.875 gallons = 3.625 gallons
Therefore, it would take 3.625 gallons of gasoline to fill the tank.

Your fortune is "You can't have everything...where would you put them all?"
The family has 3 sons and 3 daughters, for a total of 6 children.
Explanation:
The question is a problem in basic algebra which can be solved using simple logical reasoning. We are given that each daughter in the family has as many brothers as sisters, and each son has three times as many sisters as brothers.
Let's start by saying that the number of daughters is D and the number of sons is S.
If each daughter has the same number of brothers as sisters, that means D = S. But, each son has three times as many sisters as brothers, which we can express as S = 3*(D - 1), because the number of sisters for each son is the number of daughters minus one (each son doesn't count himself as a sister).
By substituting D from the first equation into the second, we get S = 3 * (S - 1), which simplifies to S = 3, and thus D = 3 as well.
So, the family has 3 sons and 3 daughters, for a total of 6 children.
