Can the Law of Sines be used to solve the given triangle?

We have three angles no sides
so eliminate any that refer to given sides and no angles
F, E, D, C,
which leaves A and B
If our information does not include (at least) one pair consisting of a side and the angle opposite it, we will not be able to apply the law of sines. We have no sides.
"AAA" is when we know all three angles of a triangle, but no sides.
AAA triangles are impossible to solve further since there is nothing to show us size ... we know the shape but not how big it is.
We need to know at least one side to get any further ... that's life!
