Answer
Step by step explanation
If AB is parallel to CD (AD EC are transversals)
angle BAD= angle ADC ( Alternate interior angles of a transversal are equal)
so angle ADC = 52 degrees
(x+52+40) degrees = 180 degrees (angle sum property of a triangle)
x+92 degree = 180 degree
x = 180-92 degree
x = 88 degree
