Height of Helicopter

Tow men measure the angle of elevation of a helicopter at the same time. One angle is measured as 35 degrees, the other as 50 degrees. If the two men are 100 feet apart and the helicopter lies over the line joining them, how high is the helicopter?

Let h be the altitude of the helicopter (which I assume is what is wanted). You will also need the cotangents of the angles of elevation.

Can you now finish this question by yourself?
