From a boat on the lake, the angle of elevation to the top of a cliff is 15°54'. If the base of the cliff is 967 feet from the boat, how high is the cliff (to the nearest foot)?

Verified answer
Angle = θ = 15 & 54 ⁄ 60 = 954 ⁄ 60 = 15.9º
tan[θ ] = (Height of Cliff) ⁄ 967
tan[15.9º] = (Height of Cliff) ⁄ 967
Height of Cliff = 275 feet
