A diver spots a sunken ship on the ocean floor 101 m away. If the ocean is 80 m deep, at what angle of depression must the diver swim to get directly to the sunken ship? Round to the nearest degree.

Answer 1

It's a right triangle with hypotenuse = 101, height -80, sin(angle) = -80/101

angle = sin^-1(-80/101)= -52 degrees.
