Question

(4) In trianglePQR. angleR=30°. angleQ=60°, angleP=90°,QR=12cm,thenPQ=?​

Answer 1

Answer:

let the angle pq and pr is x

12 = x+x

12 =2×

6=× then the angle pq and pr is 6cm

Answer 2

Answer:

In triangle pqr

P=90

R=38

QR =12cm

P =90

Q=60

90-60=30

30 cm will be PQ

12 x - x

12x

12 =2x
