To measure a stone face carved on the side of a​ mountain, two sightings

750 feet from the base of the mountain are taken. If the angle of elevation to the bottom of the face is 31° and the angle of elevation to the top is

Remember tangent of right triangle = opposite side/adjacent side ?

 

Tan 34 = top / 750        750 tan 34 = top     similarly for the bottom....subtract the two

 

750 tan34 - 750 tan 31 = height
