Question

In a trianglePRS, anglePRS = 120° a point Q is taken on PR such that PQ = QS and QR = RS.the measure of angle QPS is

Answer 1

Answer:

Step-by-step explanation:

QPS =90°

Because it divid line it make 90° angle

Answer 2

Answer:

PQ=QS

⇒∠QPS=∠QSP=x(say)

⇒∠SQR=2x (exterior angle)

=∠RSQ

From ΔQRS

120+2x+2x=180

⇒x=15

=∠QPS
