Question

In the given figure, if AB || CD, ∠APQ = 50º and ∠PRD = 127º, find x and y.

Solution

∠APR = ∠PRD  (Alternate interior angles)

50º + y = 127º

y = 127º − 50º

y = 77º

Also, ∠APQ = ∠PQR   (Alternate interior angles)

50º = x

∴ x = 50º and y = 77º

  Is there an error in this question or solution?
