Question

caluculate the angles of traingle PQR. using above pic​

Answer 1

Step-by-step explanation:

IN TRIANGLE PQR

ANGLE QRP+ ANGLE QPR+ ANGLE PQR =180°

2 ANGLE Q+ ANGLE Q+ 3 ANGLE Q =180°

6 ANGLE Q=180°

ANGLE Q= 180/6 = 30°

THEREFORE ANGLE PQR=30°

ANGLE QPR= 2×30°=60°

ANGLE QRP=3×30°=90°
