Question

A helicopter is 1500 ft. directly over the end of a lake, if the angle of depression to the other end is 24°17'.how long is the lake?​

Answer 1

Step-by-step explanation:

If we connect the helicopter, one side of the lake and the other, we will have a right triangle.

So:

longness/height = tan(90° - 60°) = √3/3

longness/1500 = √3/3

longness = 500√3 = 866 meters
