Question

The length of a vertical rod and its shadow are in the ratio 1 : √3. The angle of elevation of the sun is

(a) 30°

(b) 45°

(c) 60°

(d) 90°

Answer 1

Let AB be the rod and BC be its shadow; and \(\theta\) be the angle of elevation of the sun. 

We have,

AB : AB = 1 : √3

Let  AB = x

Then, BC = x√3

Hence, the correct answer is option (a).
