Question

In the isosceles trapezoid below,
x = [? ]°
5x-20°
2x+37°

Answer 1

x = 19

Explanation:

The lower base angles in an isosceles trapezoid are congruent , then

5x - 20 = 2x + 37 ( subtract 2x from both sides )

3x - 20 = 37 ( add 20 to both sides )

3x = 57 ( divide both sides by 3 )

x = 19
