4.) To estimate the height of a mountain above a level plain, the angle of elevation to the top of the mountain is measured to be 32°. One thousand feet closer to the mountain along the plain, it is found that the angle of elevation is 34°. Estimate the height of the mountain. (Round answer to the nearest foot.)
