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°. From a point 1000 feet closer to the mountain along the plain, they find that the angle of elevation is 34°. How high (in feet) is the mountain?
