PLEASEEEE HELPP!!!!! Attachedphoto

Answer 1

I'm not that honed in geometry, however, you are given 2 sides, and between them, is an angle. So, this may be informally written as "SAS" (or side angle side). Since, from the triangle description they gave us, the C and F are on the same position, the end, we may assume that those are to be equal.

Answer 2

As I said before, I'm not that honed in geometry, but I think its sss (side side side)? I know one of the triple letter (like sss or aaa), results in a false postulate; doesn't prove it.
