+2440 If you know all the angles but 1, you can use the triangle sum theorem, which says that the sum of the measure of the angles of a triangles is 180 degrees.
There are 2 equations that you will need, as well. They are the law of sines and the law of cosines.
The law of sines:
\(\frac{a}{\sin A}=\frac{b}{\sin B}=\frac{c}{\sin C}\)
The law of cosines:
\(c^2=a^2+b^2-2ab\cos C\)
You can solve any triangle knowing these 3 formulas.
