Question

ROS is the right angle and angle PQR and angle QOS are in the ratio 1:5 then angle QOS measure​

Answer 1

Answer: 75 AND 15 degrees

Step-by-step explanation:Let x be a common angle

i.e. POR angle : QOS angle =x:5x

now, we know sum of angles on a straight line is 180 degree

therefore, angle QOS+ angle POR +angle ROS =180 degree

5x+x+90=180⇒ 6x=90

x=90/6=15

therefore x = 15 degree

angle QOS = 5×15=75 degree

and angle POR = 15 degree
