Two points, A and B, are 526 meters apart on a level stretch of road leading to a hill.
The angle of elevation of the hilltop from A is 26°30’, and the angle of elevation from B is
36°40’. How high is the hill?
As always, draw a diagram, and review your basic trig functions.
The hill's height can be found using
h cot26°30' - h cot36°40' = 526
