Answer 2

Answer:

All the angles are 90°

Step-by-step explanation:

4y +2+5y-20=180(angles on a straight line=180°)

9y-18=180

y=198/9

y=22

Therfore POR=88+2=90°(substitute the values)

ROQ=110-20=90°

QOS=90°(vertically opposite angles)

Last angle=90°(by VOA or angles in a circle sum up to 360°)
