What is the value of the angle marked with x

Answer:
132°
Step-by-step explanation:
180-48= 132°
since those angles lie on a straight line and are parallel
we know that the sum of the corresponding side of a trapezium is 180 degrees .
if one angle is 48 degrees then let the other angle be X.
therefore,
X + 48 = 180 ( angle sum property)
X = 180 - 48
X = 132 degree
