When directly over one town, the pilot of a plane notices that the angle of depression of another town is 11 degrees. If the altimeter registers 8400 ft, what is the ground distance (in mi) between the two towns?
-
Altitude, y = 8400 ft.
Angle of Depression, Θ = 11°
Distance = x
Tan Θ = y / x
x = y / Tan Θ
x = 8400 / Tan (- 11)
x = 8400 / 0.1944
x = 43209.88
The distance between the two towns is 43,209.88 ft., or 8.18 mi.
