Question

solve plese ........

Answer 1

angle PQR + angle 120° = 180° (linear pair)

angle PQR = 180 - 120 = 60°

then, angle PQR = QPS = 60° ( alternate interior angles).......

Now, angle PRQ + angle 100° = 180° (linear pair)

angle PRQ = 180 - 100 = 80°

then angle PRQ = RPT (alternate interior angles)...

hence,

angle QPS = 60°

angle RPT = 80°
