Ack! I remember dealing with this in math. I'm not sure it can be done without knowing at least one of the angles; if you have one then you can use either the sine or cosine law to calculate the other angle.
Okay, I rooted through some of my textbooks, and found the following. Given the sides A, B, and C, where a, b, and c are the angles opposite those sides:
Cosine Law: C^2 = A^2 + B^2 - 2ABcos(c)
Sine Law: sin(a)/A = sin(b)/B = sin(c)/C
Hope that helped.

Is it given as strictly variables?
In any text that I've ever read it has always been given as strictly variables. But that probably just means that I've read far too many math books.

for that law A, B, and C are sides that are opposite of angles a, b, and c, respectively. so without any angles, that formula is useless.
Since the sides are constatly proportionate to one another ther must be a way to fond the relation of the angles, i just cant fiugure it out
AHHHHHHHHHHHHHHHH!!!! I'm two steps away from becoming an art major!!!
For the rest of you, yes we do have a group, i just thought one of you civilians would have an answer

Well, there's always the cosine law, which works if you have all 3 sides (and is mentioned above).
