Question

2) In triangle PQR.P=90°, angle Q = 30°.QR = 9.6 cm,
then find the value of PQ​

Answer 1

Answer:

4.8root3

Step-by-step explanation:

apply cos 30

therefore QP is 4.8root3

Answer 2

Step-by-step explanation:

since P=90° Q=30°

therefore R=60°

P/R=QR/PQ

90/60=9.6/PQ

90PQ=576

PQ=576/90=6.4cm.
