Question

in fig 6.9 lines PQ and RS intersect each other at a point O if angle PQR : angle ROQ = 5:7 find all the angles

Answer 1

Answer:

Step-by-step explanation:

∠POR : ROQ = 5 : 7

let the angles be 5x , 7x

5x + 7x = 180° { angles on a straight line }

12x = 180°

x = 15°

angle POR = 75° = ∠QOS

∠ROQ = 105° = ∠ROS
