Question	The angle of elevation of the sun when the length of the shadow of a pole is equal to the height of the pole is?
Type	multiple_choice
Option	45°	correct
Option	30°	incorrect
Option	60°	incorrect
Option	90°	incorrect

Let ∠BAC = θ

Let height of pole is h and length of the shadow is L.

As per question L = h

tan θ = 1 So, when tan θ is equal to 1 the angle will be 45° (Option A)
