Question

In Fig. 10.45, lines PQ and RS intersect each other at point O. If anglePOR: angleROQ=5
find all the angles.
​

Answer 1

Answer:

Explanation:

let angle POR =5X and angle ROQ =7X

Then 5X +7X =180 degree as POQ is a straight angle

so 12X = 180 degree

X = 15 degree

So angle POR =angle QOS=75Degree

and angle ROQ= Angle POS =105 Degree as opposite angles are equal.
