Answer:

x = 108°

Step-by-step explanation:

In a trapezoid, each lower base angle is supplementary to the upper base angle on the same side.

72° is a lower base angle and x the upper base angle on the same side, hence

x + 72 = 180 ( supplementary angles sum to 180° )

subtract 72 from both sides, thus

x = 108°
