The only way I know how to do this is to plot the two locations on a map
 and two take the compass bearings (or angles).  Imagine you stood in one
place, 0 degrees would be due north, 90 due east, 180 south and 270 west.
All you would have to do is measure the angle and add/subtract to the
corresponding angle depending on which quadrant the line fell into.

Do you understand this?  This may not make any sense.
