Find the angle of elevation to the top of a 150-ft flagpole from a point 50 feet from the base of the pole. Round your answer to the nearest tenth.

The flagpole and the ground form a right triangle, with height 150 ft and horizontal distance 50 ft. For the angle of elevation θ, tan(θ) = 150 ÷ 50 = 3, so θ = arctan(3) ≈ 71.6°. The correct choice is 71.6º.
