An engineer stands 50 feet away from a building with a surveying device mounted on a tripod. if the surveying device is 5 feet above the ground and the angle of elevation is 50°, find how tall is
the building.​

The building is 64.6 feet tall.

Step-by-step explanation:

To determine the height of the building, let the height from the top of the building to the top of the tripod be represented by x. So that;

Height of the building = x + 5

But,

Tan θ =

Tan =

x = 50 x Tan

  = 50 x 1.1918

  = 59.59

x = 59.59

Height of the building = x + 5

                     = 59.59 + 5

                     = 64.6 ft

The height of the building is 64.6 feet.
