Question 167332: A plane is flying at an elevation of 24000 feet.
It is within sight of the airport and the pilot finds that the angle of depression to the airport is 25 degrees
Find the distance between the plane and the airport.
Find the distance between a point on the ground directly below the plane and the airport

tan 25=24000/y where y is the distance between a point on the ground below
:
: the plane and the airport---->24000=tan 25 (y)----->y=51,502ft
:
sin 25=24000/x where x is the distance between the plane and the airport
:
: 24000=sin 25(x)-----y=56,738ft
