Question

∆PQR, angle Q=30°, angle R-90° and the length of the hypotenuse is 20cm, what will be the length of the other two sides?​

Answer 1

Answer:

In given right angle 

∠P=90°

 QR=12cm

BY using 30°−60°−90° triangle, we get special relationship between its sides.

All of us know in right angle triangle hypotenuse is longest side.

So,  longest side=12m

       shortest side=212=6m
