Question

What is the measure of X?

108°
108°
2x
2x
72°
144
36
360°

Answer 1

We know that the interior angles of a trapezoid
add up to 360 degrees.
Write out an equation to represent this situation;
108+108+2×+2x=360
216+4×=360
4×=360-216
4x=144
x=144/4
×=36
Therefore, the measure of × is 36 degrees.

Answer 2

36°

Explanation:

108°+ 108°+ 2x+ 2x =360°

4x +216° = 360°

4x= 360°- 216°

Just X= 144°/4

=36°

2x= 2(36)

= 72°
