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? Last edited by skipjack; April 8th, 2017 at 12:52 AM.

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 acuteangled.
