I'm going to assume you've learn sin, cos, and tan. To find a you must do:
sin^{ - 1}  =  \frac{a}{12}
Once you find a, you can use the Pythagorean Theorem to find b:
{a}^{2}  +  {b}^{2}  =  {c}^{2}
Or you can do:
cos^{ - 1}  =  \frac{b}{12}
You can find these functions on a scientific calculator. Let me now if you need more help.
