Um..You solved this topic CPhill, but I still have a question.

Using the Law of Sines

sin B            sin C

____    =    _____

AC             AB

sin 145           sin C

______   =    _______

2035             1017.15

sin C   =  (1017.5) * sin (145) / 2035

arcsin   [ (1017.5) * sin (145) / 2035 ] =  C = 16.67° ≈ [1.67 x 10^1 ] °

This was your solution...How did you solve that on a calculator? I'm in degree mode and I'm entering the right numbers, but it keeps giving me an error. I tried using the calculator on this website as well, but it gave me an invalid arguement...
