Variables used:A,B,C,D,E,F,G
This program solves a triangle given three of the sides and angles with at least one side.
It uses the laws of sines and cosines, plus the fact that the angles in a triangle add up to
180 degrees.  There are five cases: (1)a,b,c  You know the sides.  It finds the angles.  
(2)a,b,A  You know two sides and the angle opposite one of them.  This sometimes has more 
than one solution; if so, both will be displayed.  (3)a,b,C  You know two sides and the angle
between them.  (4)a,B,C  You know two angles and the side between them.  (5)a,A,B You know 
two angles and the side opposite one of them.
This program will set your calculator into degree mode, if it isn't already.  Calculus 
students take note.
