from a point on the ground 152.3 feet away from the foot of a flagpole. the angle of elevation of the top of the pole is 31 degrees 46 minutes. how high is the flagpole?
46 min = 46/60° = 23/30 °
Using the tangent function, we have
tan [31 + 23/30] = H / 152.3 where H is the pole height ...... solve for H
152.3 * tan [ 31 + 23/30] = H = about 94.3 ft
