The trapezoid is an isosceles trapezoid so |dw:1400717050041:dw|

anonymous · Answer

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$$8a - 3 = 7a + 2$$

anonymous · Answer

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