A survey team is trying to estimate the height of a mountain above a level plain. From one point on the plain, they observe that the angle of elevation to the top of the mountain is 31 degrees. From a point 2000 feet closer to the mountain along the plain, they find that the angle of elevation is 36 degrees.

How high is the mountain in feet?

Thanks in advance.
