An airplane flying at an altitude of 32000 feet is headed toward an airport. To guide the airplane to a safe?
landing, the airport landing system sends radar signals from the runway at a 10 degree angle above the runway. Measured along the ground, how far is the airplane from the airport runway to the nearest foot?
----
Draw the picture.
You have a right triangle with a 10 degree angle at the ground
and a 32000 ft side opposite the 10 degree angle.
----
Solve for the base.
----
tan(10) = 32000/base
base = 32000/tan(10) = 181481.0182 ft.
