Question

A boy standing at a distance of 48 meters from a building observes the top of the building and makes an angle of elevation of 30 degree . find the height of the building

Answer 1

In solving this problem, we are going to use Tan∅


Tan∅ = Opposite/Adjacent


Opposite = h, the height of the building

Adjacent = 48m


∅ = 30 degrees


Tan 30 = h/48



h = 48 Tan 30


   = 27.7 m


The height of the building = 27.7 m



NOTE:

The most accurate way of getting the actual height of the building is to add the height of the boy to 27.7 m


The height of the building would be =  27.7m + the height of the boy
