The image you uploaded contains a set of problems that ask to solve triangles based on given values of sides and angles, according to the standard principles of trigonometry. These problems provide various combinations of side lengths (denoted by $a$, $b$, $c$) and angles (denoted by $\alpha$, $\beta$, $\gamma$) for triangle $ABC$.

If you'd like, I can solve one or more of these triangles step by step. Could you specify which number you'd like to work on first? Alternatively, I can start with the first one and proceed from there.
