Question

In figure angle ROS is a right angle and angle POR and angle QOS are in the ratio 1:5 then find angle QOS

Answer 1

Answer:

QOS=75°

Step-by-step explanation:

POR+ROS+SOQ=180° ( straight line)

POR+90°+SOQ=180°

POR+SOQ=180-90

POR+SOQ=90°

1x+5x=90°

6x=90°

x=90/6

x=15°

5x×15

75

hence

QOS=75°
