Question

From a top of a building 180 m height the angle of depression of a bus an the ground is found to be 60, Find the distance between the foot of the building and the bus

Answer 1

Step-by-step explanation:

Given from the top of the building ,the angle of depression of a point on the ground is 60°.The height of the building... is 180..

To find:- the Distance between the foot of the building to the bus. .

=>Let AB height of the building=180 m.

Angle ACB=60°.

Let BC=x then distance of the building between foor or bus.

From ∆ABC

AB/BC =tan 60

==>180/x=√3

x=60√3
