Question

Ab is a mirror,pq is ancient ray and qr is reflected ray if angle pqr is 112° find pqa and rqb

Answer 1

Answer:

As we know that,

angle of incidence = angle of reflection (Law of reflection)

⇒∠PQA=∠RQB

Now,

∠PQA+∠PQR+∠RQB=180°

⇒∠PQA+∠PQA+112°=180°(∵∠PQA=∠RQB)

⇒2∠PQA=180°−112°

⇒∠PQA=268°=34°
