Question

Reed is snorkeling on the surface to the ocean, 22 feet from an anchored boat. The anchor is on the ocean floor, 34 feet away from Reed. What is the angle of depression between Reed and the anchor? A. 65. B. 40. C. 50. D. 90.

GPT-5 mini · Answer

Let θ be the angle of depression. In the right triangle, the horizontal distance is 22 and the line-of-sight (hypotenuse) is 34, so

cos θ = adjacent/hypotenuse = 22/34 = 11/17.

θ = arccos(11/17) ≈ 50°.
