Question

answer must be=60 degree

Answer 1

Answer:

Step-by-step explanation:

Answer 2

Answer:

Extend OP such that it meets QR at A

angle APQ=70° ____(linear pair)

angle RAP=130°____(OA||RS, corresponding angles)

angle PAQ=50°____(linear pair)

In ΔPAQ,

angle PAQ+ angle APQ+ angle PQA = 180°

angle PQA = 180°-(70°+50°)

angle PQA = 60°

that is angle PQR =60°
