Angle 1 and angle 2 form a linear pair. if m angle 2 = 67. what is m angle 1
Final answer:
The measure of angle 1 can be found by using the fact that angle 1 and angle 2 form a linear pair. By setting up an equation and solving, we find that angle 1 measures 113 degrees.
Explanation:
To find the measure of angle 1, we need to understand that angle 1 and angle 2 form a linear pair. A linear pair of angles is formed when two adjacent angles are supplementary, meaning they add up to 180 degrees. So, angle 1 + angle 2 = 180 degrees. Given that angle 2 measures 67 degrees, we can substitute this value into the equation to find angle 1: angle 1 + 67 degrees = 180 degrees. Solving for angle 1, we get angle 1 = 180 degrees - 67 degrees = 113 degrees.

what rotation will map the figure onto itself?
The correct answer is 180° about the center.
To map the given figure onto itself, we need to find the rotational symmetry. Let’s analyze the “X” shape:
A 90° rotation would not work because it would overlap the arms of the “X.”
Similarly, a 270° rotation would also result in overlapping arms.
A 45° rotation would not preserve the original shape due to the asymmetry of the “X.”
However, a 180° rotation about its center will bring each arm of the “X” back to a position occupied by another arm, effectively mapping it onto itself. An “X” has rotational symmetry at 180°; every half turn gives us an identical view.
The correct answer is 180° about the center. This specific degree of rotation is required due to the symmetrical nature of an “X” shape where each arm aligns with another after being rotated by this angle.

find the area of one segment formed by a square with sides of 6 inches inscribed in a circle (hint: use the ratio of 1:1:square root of 2 to find the radius of the circle)
To find the area of a segment formed by a square inscribed in a circle, calculate the circle's radius from the square's diagonal, then find the circle's area and divide by 4. The area of one segment is approximately 14.14 square inches.
Explanation:Finding the Area of a Segment in an Inscribed Circle
To find the area of one segment formed by a square with sides of 6 inches inscribed in a circle, we first need to determine the radius of the circle. The given ratio of 1:1:square root of 2 is key here. In a right-angled triangle with sides of equal length (1:1), the hypotenuse will be the square root of 2, according to the Pythagorean theorem. Since the diagonal of the square is the diameter of the circle, and the square has sides of 6 inches, we can calculate the diameter (d) of the circle as:
d = 6 inches × square root of 2
Therefore, the radius (r) is half of that:
r = (6 inches × square root of 2) / 2 = 4.24 inches (approximately)
With the radius, we can calculate the area (A) of the circle:
A = πr² = 3.1415927… × (4.24 inches)²
A ≈ 56.55 square inches (to two significant figures)
Now, the area of one segment is the area of the circle divided by the number of segments, with this particular scenario having 4 equal segments:
Area of one segment = Total area / 4
Area of one segment ≈ 56.55 square inches / 4 = 14.14 square inches (approximately)
The area of one segment formed by the inscribed square in the circle is approximately 14.14 square inches.
The area of one segment of a circle formed by an inscribed square with sides of 6 inches is approximately 14.14 square inches, calculated by first finding the radius of the circle using the 1:1:√2 ratio and then using the area formula A = πr².
Explanation:To find the area of one segment formed by a square with sides of 6 inches inscribed in a circle, we first need to calculate the radius of the circle using the given ratio of 1:1:√2. In an inscribed square, the diagonal is equal to the diameter of the circle. The diagonal of the square can be found using the Pythagorean theorem (a² + b² = c²) where a and b are the sides of the square and c is the diagonal. In this case, the diagonal is √(6² + 6²) = √(36 + 36) = √72 = 6√2 inches, which is also the diameter of the circle.
Thus, the radius (r) of the circle is half of the diameter, r = 6√2 / 2 = 3√2 inches. Now we can compute the area (A) of the circle using the formula A = πr². Plugging our radius into this formula gives us A = π(3√2)² = π(18) ≈ 56.55 square inches.
The circle is divided into four equal segments by the square, so the area of one segment is one-fourth of the total area of the circle. Therefore, the area of one segment is approximately 56.55 / 4 = 14.14 square inches.

If a triangle is equilateral then it has 3 congruent angles proof
Allow ABC to be an
equilateral triangle so AB = AC = BC. Let X be the midpoint of BC, AX is the
median of BC, and BX = CX. Look at triangles BAX and CAX. Obviously, AX = AX since
AB = AC and BX = CX, subsequently by SSS Congruence Test, we have that
triangles BAX and CAX are congruent. Therefore, corresponding angles are
congruent so <ABX = <ACX. Because <ABX and <ABC are the same angle,
they are obviously congruent, and then <ABX = <ABC. Likewise, <ACX and
<ACB are the same angles so <ACX = <ACB. Then, <ABC = <ACB. Please
note that <ABC = <B and <ACB = <C. Therefore, <B = <C.
At present, disregard AX and let Y be the midpoint of AC.
Then BY is the median of AC. Then AY = CY. Evidently, BY = BY. Because AB = BC, we see that triangles ABY
and CBY are congruent by SSS. Then corresponding sames are congruent so <BAY
= <BCY. Since <BAY and <BAC are the same angles then <BAY =
<BAC. Similarly, <BCY = <BCA since they are the same angles. Then
<BAC = <BCA. Note that <BAC = <A and <BCA = <C. Therefore,
<A = <C.
Thus, <A = <C = <B. So all the angles are congruent.
The diameter of a circle is 8 centimeters. a central angle of the circle of the circle intercepts an arc of 12 centimeters. what is the radian measure of the angle?
The radian measure of the angle is 1.5 radians.
Explanation:To find the radian measure of the angle, we need to determine the length of the arc intercepted by the angle. We know that the diameter of the circle is 8 centimeters, so the radius is half of that, which is 4 centimeters. The circumference of the circle is given by the formula C = 2πr, where r is the radius.
In this case, the arc length intercepted by the angle is 12 centimeters. We can use the formula for the circumference to find the radian measure of the angle.
C = 2πr
12 = 2π(4)
12 = 8π
Dividing both sides of the equation by 8, we get:
π = 1.5 radians

Find the measure of each interior angle
Decagon in which the measures of each interior angles are x + 5, x + 10, x + 20, x + 30, x + 35, x + 40, x + 60, x + 70, x + 80, and x + 90
To find each interior angle of a decagon given as expressions with x, we sum the expressions and set equal to 1440 degrees, the total sum of interior angles. Solving for x, we find x=100 and then substitute to find each angle.
To find the measure of each interior angle of a decagon where the angles are given as expressions involving x, we must use the fact that the sum of interior angles in a polygon is (n-2)180 degrees, where n is the number of sides in the polygon. For a decagon, which has 10 sides, the sum would be (10-2)180 = 1440 degrees.
x + 5 + x + 10 + x + 20 + x + 30 + x + 35 + x + 40 + x + 60 + x + 70 + x + 80 + x + 90 = 1440
Combining like terms, we find that:
10x + 5 + 10 + 20 + 30 + 35 + 40 + 60 + 70 + 80 + 90 = 1440
10x + 440 = 1440
10x = 1440 - 440
10x = 1000
x = 100
Once x is found, we substitute back into each angle expression to find the measure of each interior angle:
x + 5 = 105 degrees
x + 10 = 110 degrees
x + 20 = 120 degrees
x + 30 = 130 degrees
x + 35 = 135 degrees
x + 40 = 140 degrees
x + 60 = 160 degrees
x + 70 = 170 degrees
x + 80 = 180 degrees
x + 90 = 190 degrees
