Question 582651: 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?

You can put this solution on YOUR website! 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.
