**MathMate**, Friday, September 11, 2009 at 7:35pmThe angle PAQ is the angle of elevation viewed from the ship, which is the same as the angle of depression viewed from the airplane (8°20'). The same for ship B.

This is because the angles of elevation and depression are alternate angles between two parallel lines.

I agree with the two calculations above using H/tan(θ) for the horizontal distance, and the answer of 13.143 km.
