Question

A shark is swimming 28 ft below sea level. If the angle of depression from a boat on the water to the shark is 19 degrees, what is the horizontal distance between the boat and the shark?

Answer 1

81,3 ft to the nearest tenth.

Explanation:

Tan 19 = 28 / h where h = the horizontal distance.

h = 28 / tan 19

h = 81.3 ft.
