review the definition of cot(x). You will see that if the height is h,
h*cot27° - h*cot29° = 1000
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 27∘. From a point 1000 feet closer to the mountain along the plain, they find that the angle of elevation is 29∘.
How high (in feet) is the mountain?
