An observer (O) is located 900 feet from a building (B). The observer notices a helicopter (H) flying at a 49° angle of elevation from his line of sight. How high is the helicopter flying over the building?

Respuesta :

The height of the helicopter flying over the building is 1035 ft

How to find the height of the helicopter(height of right angle triangle)?

The height of the helicopter is the opposite side of the right triangle.

The adjacent side of the right triangle is the distance of the observer from the building.

Therefore,

tan 49 = opposite / adjacent

Therefore,

tan 49 = h / 900

cross multiply

h  = 900 × tan 49

h = 1035.3315665

Therefore,

height of the helicopter = 1035 ft
