Harman [31]

Given :

A building is of unknown height. At a distance of 400 feet away from the building .

An observer notices that the angle of elevation to the top of the building is 35º and that the angle of elevation to a poster on the side of the building is 15º .

To Find :

How far is the poster from the roof of the building .

Solution :

Height is given by :

h=d\times tan\theta

( Here , \theta is angle of elevation )

So , height of tower :

H=400\times tan 35^o\\\\H=280.08 \ feet

For height of poster :

h=400\times tan 15^o\\\\h= 107.18\ feet

Therefore , distance of poster from the roof of the building is :

( 280.08-107.18)  =  $$172.9\ feet

Hence , this is the required solution .
