Question

In the figure, if AB is parallel to CD, then x=?

A. 48
B. 38
C. 30
D. 42​

Answer 1

x = 48

Explanation:

since AB and CD are parallel then

∠ AEF and ∠ DFE are same- side interior angles and sum to 180° , so

72 + 60 + x = 180 , that is

132 + x = 180 ( subtract 132 from both sides )

x = 48
