I'm having trouble solving this problem. I've been trying for hours but still have not come up with the solution. I'd really appreciate it if someone could give me a hand. Thanks in advance.
Note: I drew the picture myself so it might differ from the original.

Is the angle at a suppose to be a central angle, the vertex at the center?

Yeah, sorry. I know my drawing's bad.

In that case the measure of angle a is twice that of b.

So that means that b is 60 and a is 120 right?

May I suggest you get an Helix-Oxford geometry set; about 5 bucks...
It'll help you solve many similar problems.
