Question

Hellpppp? :(Trapezoid WXYZ is isosceles. Angle WZY measures (8a – 3) and angle ZYX measures (7a + 2). Find the measure of angle WZY.

Answer 1

A. 43°
B. 143°
C. 5°
D. 37°

Answer 2

The trapezoid is an isosceles trapezoid so

Answer 3

That means that the 2 bottom angles are equal and the 2 top angles are equal so since we know the equation for both the bottom angles we can set them equal to each other\[8a - 3 = 7a + 2\]

Answer 4

This allows us to solve for a. With a we can solve for WYZ!

Answer 5

Using this answer for \[WZY = 8a - 3\] we can solve for the angle measurement
