Q1 of 28 Page 93

The shadow of a vertical pillar is equal to the height of the pillar, then the angle of elevation of the Sun will be


Let AB is a pillar, AC is the shadow of the pillar, and angle of elevation of the pillar from point C is ∠ACB = θ.


Given, AC = AB


The side with angle of elevation is called base and side opposite to angle of elevation is called height of triangle.


We know that,



tan θ = 1 (Given: AC = AB)


θ = 45o
