The angle of elevation to the top of a flagpole measured by

The angle of elevation to the top of a flagpole measured by a digital protractor is 57.4 degree from a point on the ground 75 feet away from its base. Find the height of the flagpole. The height of the flagpole is approximately ft.

Solution

Apply tangetn formula

tan(theta) = height/base

tan57.4 = h/75

h = 75*tan57.4 = 85.60 ft
