I need help solving an oblique triangle with the laws of sin

I need help solving this please, it's a sort of like a project that my partner and I need to orally present in front of the class and we both can't figure it out, We need to show all work by memory and we really need help, we must use the laws of sine and cosine. Thank You for your help!

So far what I have done is: SinA/a = SinB/b , but I can't figure it out at all after that, I am completely lost.

It looks to me like you just need to use the law of cosines once.
