Let ∠POR = 5x and ∠ROQ = 7x
Now,
∠POR + ∠ROQ = 1800 (Angles on the same line)
5x + 7x = 180
12x =180
x= 150
Therefore, ∠POR = 750 and ∠ROQ = 1050
Now,
∠POR = ∠SOQ (Vertically opposite angles)
∠ROQ = ∠POS (Vertically opposite angles)
Therefore, ∠SOQ = 750 and ∠POS = 1050
hope it's helps you

Let angle por be 5x
and angle roq be 7x
so, 5x+7x=180. (linear pair angles)
=>12x=180
=>x=180/12
=>x=15
so, 5x=5(15)=75
7x=7(15)=105
so, angle por=angle soq=75
and, angle roq=angle pos=105.
