Question

9. angle PQR and angle POS are linear pair of angles. If
11 angle POR = 9 angle POS, then find angle PQR and angle POS.​

Answer 1

Answer:

Step-by-step explanation:

Given:

anglePQR+anglePOR=180°(Linear pair)

anglePQR=180°-anglePOR........... eq(i)

11×anglePOR=9×anglePOS

put the value from eq(i)

11×anglePOR=9×(180°-POR)

11POR=1620°-9POR

20POR=1620°

POR=81° andPQR=99°
