A salvage ship’s sonar locates wreckage at a 12 degree angle of depression. A diver is lowered 40 meters to the ocean floor. To the nearest meter how far does the diver need to walk along the ocean floor to the wreckage?

  1. tan 12 = 40/d
    d = 40/tan 12 = 188 meters !

    If that diver is wearing a hard hat, he is going to be a wreck himself by the time he gets there and it will take so long that he will need to make decompression stops upon ascent to avoid getting the bends.
    Move the stupid ship !
