Please help me!The angle of elevation of the top of a tower to a point on the ground is 61°. At a point 600 feet farther from the base, in line with the base and the first point and in the same plane, the angle of elevation is 32°. Find the height of the tower.

A:
Answer: 573.6 ftStep-by-step explanation:The mnemonic SOH CAH TOA reminds you of the relationship of right triangle sides and angles: Tan = Opposite/AdjacentThis tells us ... tan(61°) = (height)/(distance to first point) or distance to first point = height/tan(61°)Likewise, ... distance to second point = height/tan(32°)Then the difference of the distances is ... distance to second point - distance to first point = height/tan(32°) -height/tan(61°) 600 ft = height × (1/tan(32°) -1/tan(61°))Dividing by the coefficient of height, we have ... height = (600 ft)/(1/tan(32°) -1/tan(61°)) ≈ (600 ft)/(1.04603) ≈ 573.6 ft
