Pretty sure it's 180 degrees and not 160 due to angle C being a vertical angle.

To theCEO: I can certainly see the attachment. I am quite surprised that you cannot.

Thanks for letting me know truplayer. I found that I had to hit the compatibility button (internet explorer). Strange, I have never done this in the past. Makes me wonder all the things I may have missed on all my favorite sites!

Are you sure you gave us all the information :). For the answer to be 160degrees, something is missing!

a+b+c=x+y+z, with x, y and z being the opposite angles to a, b and c resp.
knowing that a+b+c+x+y+z=360, then a+b+c=360/2=180
