The angle of elevation from a point on the ground to the top of a pyramid is 23^•(degree)40^’(minutes). The angle of elevation from a point 112 ft farther back to the top of the pyramid is 15^•30’. Find the height of the pyramid.

Answer 1

Draw a diagram and review your basic trig functions. If the height is h, then
h cot 15°30' - h cot23°40' = 112
