Because it was early and I was tired.

I realize you are a moderator, but if you have so many problems with my posts why don't you just post the answer yourself?

My first post in this thread hasn't been answered by TotalMathMan, and I like to give the first person who answers (yourself in this instance) a chance to improve their answer.

There are various ways to do the problem. I would use c = a*cos(B) + b*cos(A).

There are two possible answers, as it can't be assumed that the triangle is acute-angled.
