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 57.8° from a point on the ground 66 feet away from its base. Find the height of the flagpole.

(round to two decimal places as needed)

Solution

Let the height be h feet.

tan 57.8= h/66

h=66 tan 57.8

h=104.81 feet

The height of the flagpole is 104.81 feet
