Question

If the height of a vertical pole is √3 times the length of its shadow on the ground, then the angle of elevation of the sun at that times is
A. 30°

B. 60°
C. 45°
D. 75°

Answer 1

Answer:

Consider the height of tower be √3 h

∴ height of shadow =h .

In a triangle ABC,

tan ∠ACB =  

tan ∠ACB = √3

∠ACB = 60°.

Therefore, angle of elevation is 60° (∵ tan 60° = √3)

Answer 2
