You can put this solution on YOUR website!
Find angle A using the Law of Sines:
720/sin(46) = 500/sin(A)
sin(A) = 500*sin(46)/720 =~0.49954
A = 29.9696º
--> heading C to A = West 30º South
------------------------------------------
Whose idea are these "headings?"
N 44 W should be 316º
The heading from C to A should 240º
The people writing the textbooks should stick to subjects they understand.
