Question

In trianglePQR angleP=2 angleQ and 2 angleR=3 angleQ. calculate the angles of triangle PQR​

Answer 1

Answer:

∠Q=360/9=40°

∠p=2∠Q=2*40=80°

∠R=3/2∠Q=3/2*40=60°

Step-by-step explanation:

∠P=2∠Q

2∠R=3∠Q

∠R=3/2∠Q

∠P+∠Q+∠R=180°

2∠Q+∠Q+3/2∠Q=180°

1/2( 4∠Q+2∠Q+3∠Q)=180°

9∠Q=180*2=360

∠Q=360/9=40°

∠p=2∠Q=2*40=80°

∠R=3/2∠Q=3/2*40=60°
