Question 909822: A pilot, flying at an altitude of 5000 feet, wishes to approach the numbers on a runway at an angle of 15°. Approximate, to the nearest 100 feet, the distance from the airplane to the numbers at the beginning of the descent.

You can put this solution on YOUR website! A pilot, flying at an altitude of 5000 feet, wishes to approach the numbers on a runway at an angle of 15°. Approximate, to the nearest 100 feet, the distance from the airplane to the numbers at the beginning of the descent.
----
Draw the picture.
You have a right triangle with height = 5000 ft
and you have a 15 degree base angle.
-----
Determine the hypotenuse::
sin(15) = 5000/hypotenuse
------
hypotenuse = 5000/sin(15) = 19318.52 ft
