Question

If the shadow of a pole 3 metre high is 3√3 metre long, then the angle of elevation of the sun is

(a) 30°

(b) 45°

(c) 60°

(d) 75°

Answer 1

Correct option is (a) 30°

Height of the pole = 3 m

Length of shadow cast on ground = 3√3m

Let “θ be angle of elevation”.

According to the question,

\(\tan \theta = \frac{3}{3\sqrt 3}\)

\(= \frac 1{\sqrt 3}\)

\(\therefore \tan \theta = 30° \)
