A ship’s sonar detects a submarine 880 feet below a point on the ocean’s surface 1450 ft dead ahead of the ship. To the nearest degree, find the angle x.

Answer 1

I can't see your diagram and don't know where x is, but I will assume that the data results in a right-angled triangle with x as the angle of depression from the ocean's surface to the sub.

tanx = 880/1450 = ...
x = appr 31.25°
