Question

in the give figure AB parallel to CD, angle APQ-60degree angle PRD-137degree.find x and y​

Answer 1

Answer:

it is given that ABII CD

so. APQ = PQR ( alternative interior

angles )

. PQR = 60 degree

PRD +/_PRD = 180 ( linear pair)

PRD = 180 - 137

PRD = 43

in Triangle PQR

PQR + / QPR +/_PRQ = 180 ( Angle sum property of triangle )

60 +/_ QPR + 43 = 180

QPR = 180 - 103

= 77
