Question

Find the value of x in the trapezoid below. Show equations and all work that leads to your answer.

Answer 1

Since the side is a transversal to the parallel bases, the angles formed are supplementary. This lets you write the relation

... (3x-5)° + (5x+13)° = 180°

... 8x +8 = 180

... x = (180 -8)/8 = 21.5

The value of x is 21.5.
