I am completing confused!
Answer by scott8148(6628) (Show Source): You can put this solution on YOUR website!
the altitude of the helicopter, the distance to the landing area, and the ground; form a right triangle

the angle between the altitude and the distance (which is the hypotenuse), is the complement of the angle of depression

let x=distance ___ cos(90�-24�20')=1 mi/x ___ x=5280/cos(65�40')
