Answer 1

Given - angle AP b is equals to 50 degree

angle PRD is equal to 127 degree

Proof- since a b is parallel to CD and PQ is a transfer shall therefore angle A PQ is equal to angle pqr therefore x is equal to 50

x = 50°

Now an angle PR q is equals to 127 degree - 180 degree because they are on a same line 53 °

Hence by angle sum property of a triangle angle y is equals to 50 + 53 - 180 = 77

hence y= 77°
