Reed is snorkeling when he spots a stingray resting on the bottom of the ocean floor. He is on the surface of the water looking down. The water is 22 feet deep and the diagonal distance from him to the fish is 34 feet. Use the inverse of cosine to find the approximate angle of elevation with which he is looking at the fish.(1 point)

Answer 1

40°

To find the angle of elevation, we can use the inverse cosine function.

cos(angle) = adjacent/hypotenuse
cos(angle) = 22/34
angle = arccos(22/34)
angle ≈ 40°

Therefore, the approximate angle of elevation with which Reed is looking at the fish is 40°.
