Question

The shadow of the vertical pole is 1/root3 of its height. Show that the suns elevation is 60dgree

Answer 1

Let ∠ACB be the angular elevation of the sun.

Let AB be the pole and BC be its shadow.

let AB = h
Let BC = h3√now, tan ∠ACB = AB/BC⇒, tan ∠ACB = h/h3√ = 3√
 tan ∠ACB = tan 60 °⇒∠ACB = 60°

so, angular elevation of Sun = 600

Answer 2

Step-by-step explanation:

tan theta = p/b

tan theta = h/1root3 h

tan theta = root 3 h/h

tan theta = root 3

so theta = 60 degree
