Question

in the fig,if anglePOS +angleQOS+angleQOR=302 then anglePOS=?​

Answer 1

Answer:

Here we are given that POS is a straight line

Explanation:

POQ + ∠QOR + ∠ROS = 180° (straight angle) ⇒ 60° + 5x – 20° + 40° = 180° ⇒ 5x + 80° = 180° ⇒ 5x = 100° ⇒ x = 20° ∠QOR = 5x – 20° = 5 x 20° – 20° = 80°
