## Angle of Elevation and find Height & Distance : Solved Examples

 Angle of Elevation Angle of Depression

At a point 10m away from the foot of a building, the angle of elevation of the top of building is 60° find the height of building
Let AB is the building. B is the foot and A is the top of building. C is the point on the ground at which the angle of elevation is 60°

so we get
CB = 10m
∠ BCA = 60°
AB = ?

In the right △ ABC

We know that Tan θ = Opposite Side / Adjacent Side

 tan 60° = ABBC

 √ 3 = AB10

 AB = 10 x √ 3

Value of  3  is 1.73 so,

AB = 10 x 1.73 = 17.3

AB = 17.3m is the height
