Answer 1

Answer:

60°

Step-by-step explanation:

Extend OP to A and RS to B such that OA║ SB

∠BRO = 50 = 180 - 130 (linear pair)

let the point where PQ and RS intersect be L

∠BLP = 110 (corresponding angles)

∠PLR = 70 = 180 - 110 (linear pair)

In Δ QLR, through Angle sum property

∠PQR = 180 - (70 + 50) = 180 - 120 = 60
