Question

In the fig. ,a tower PQ is 30m high and the length of its shadow QR is 30√3m . Find the sun's altitude

Answer 1

i hope this will usful to u

Answer 2

The opposite side is PQ 30 cm.
The adjacent side is QR 30 root3 cm.
Then tan theta=opp/adj=30/30root 3=1/root3 .
tan30=1/root3.So the angle of elevation of sun's rays is 30°.
