Question

plz tell me the answer correctly friends​

Answer 1

Answer:

(b) 75°

Step-by-step explanation:

∠POR+∠ROQ=180° (Linear pair of angles)

But ∠POR:∠ROQ= 5:7   (Given)

Therefore,∠POR= $\frac{5}{12} * 180= 75$°

 Similarly, ∠ROQ=  $\frac{7}{12} *180=105$°

Now, ∠POS=∠ROQ=105 ° (Vertically opposite angles)

and ∠QOS=∠POR=75°  (Vertically opposite angles)

Hence, ∠QOS=75° because of vertically opposite angles.
