Question

What will be the angle of elevation of the sun when the length of shadow of a vertical pole is equal to its height

Answer 1

Answer: 45°

Step by step explanation:

Let the angle of elevation be ∅

Let the height of pole be h.

Let the length of shadow be x.

As per the ques,

h = x

In ∆ ABC,

tan ∅ = AB/BC = h/x = 1

tan ∅ = 1

tan ∅ = tan 45

∅ = 45°

Answer: 45°
