To find the angle of elevation, you can use the tangent function in trigonometry, which is tan(θ) = opposite/adjacent. Here, the opposite side is the height of the tower (111 feet) and the adjacent side is the distance from the tower (62 feet). So, tan(θ) = 111/62. Using a calculator to find θ, you get θ = arctan(111/62) ≈ 60.8 degrees.
