1. The problem statement, all variables and given/known data I have to find the measures of the angles x & y. 2. Relevant equations Sine Law Cosine Law 3. The attempt at a solution First thing I tried to do was find the measure of the angle @ A. a/SinA = c/SinC 66/SinA = 25/Sin10.5 and then I end up with 28 degrees for the angle @ A. 28 degrees is obviously wrong. I'm ending up with an error and I can't understand why because so far as I understand my procedure is correct. I want to solve for angle A, then because I already have angle C I can solve for angle B. From angle B I could find the angle next to (x), thereby finding x becasue the sum of the two would be 180.
