You can put this solution on YOUR website!
You have one angle and three sides?
Use the law of sines to get the other two angles.
I'm assuming that angle a is associated with side 80?
sin%28a%29%2F80=sin%28b%29%2F%286x-9%29=sin%28c%29%2F%287x-8%29
You can also solve for c once you know a and b since,
a%2Bb%2Bc=180
