The Law of Siness is sinA = sinB= sinC

---- ---- ----

a b c

and the other one was actually the Law of Cosines, which is:

c squared= a squared + b squared - 2ab cosC

cos C= a squared+ b squared- c squared divided by 2ab.

What I still don't quite know is when these laws need to be used...

Thanks!
