Question

7. In the figure PQ || SR and PQ = QR. Find 2x + y.

Kindly tell me, how to solve this particular problem... ​

Answer 1

Answer:

y 120 and x 60 I hope its help

Answer 2

given - PQ=QR

so opposite angles are equal to opposite side in a triangle

angle QPR= x = Angle PRQ

so in Triangle PQR

sum of all angles= 180

x+x+y= 180

2x+y=180

Hence proved
