A scuba diver located 20 feet below the surface of water spots a shipwreck at a 70 degree angle of depression. After descending to a point 45 feet above the ocean floor, the diver sees the shipwreck at a 57 degree angle. Draw a diagram to represent the situation, and determine the depth of the shipwreck.

  1. assuming a level ocean floor, then
    if the wreck is at a distance x from the point directly below the diver,
    45/x = tan 57°

    If the diver started at a point h above the floor, then
    h/x = tan 70°

    The depth of the ship is 20 + h
