Quote:
If we extend RP further down, lets call the extended line PT.
Now, as PQ is parallel to RS, Angle QPT is also 120 degree(corresponding angles)
Since the sum of angles in a straight line is 180 degree,
x + 20 + QPT = 180
x = 180 - 20 - 120 = 40(Option E)

As PQ is parallel to RS angle
RPQ +PRS= 180
so RPQ=60
hence X=40
