Question

if the shadow of the person standing in sun is root 3 times its height then the angle of the elevation of sun is ?

Answer 1

Consider the height of tower be h ∴ height of shadow =√3h . In a triangle ABC, 

tan ∠ACB = h / √3h

tan ∠ACB = 1 / √3

∠ACB = 30°. Therefore, angle of elevation is 30°.
