I need help solving an oblique triangle with the laws of sine and cosine please! :)

[AASSTheGuy]

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.

You need to use the law of cosines for triangles (look it up in Google or your textbook)

That law says:

c² = a² + b² - 2ab*cos(C).

I'll leave it to you to find out what does 'a', 'b', 'c' & 'C' mean for a given triangle.

Please share your work with us .

If you are stuck at the beginning tell us and we'll start with the definitions.
