Question

plz tell . the answer of this question

Answer 1

AB || CD
then,
by alternate interior angles
angle APC = angle x
so,
angle x = 60°




again by using alternte interior angles
angle PRD = angle APR

so,
angle APR measures 137°

angle APR = y + 60°
137° = y +60°
y =137° - 60°
y = 77°.

Answer 2

Angle APQ = angle PQR ( alternate angles)
So angle PQR = x = 60
We know that exterior angle of a triangle = sum of the two interior opposite angles.
Hence PRD = QPR + PQR = x+y
137 = y + 60
Y = 137-60= 77
