An airplane is flying 38,900 ft above the ground. angle of depression from the plane to the base of the building is 4.3°. how far must a plane fly horizontally to be directly over the building?

Height of the airplane above the ground = 38,900 ft.

Angle of depression from the plane to the base of the building = 4.3°.

So, we could apply tangent trigonometric ratio:

tan 4.3° =

0.07519 =

On cross multiply, we get

0.07519 x= 38,900.

Dividing both sides by 0.07519, we get

x= 517356.03 ft.

step-by-step explanation:

4000*70 = 280000

280000-(2000*90) = 100000

4000-2400 = 1600

100000/1600 = 62.5
