Finally, let's see what the different trig functions tell us about
non-right triangles. In a triangle with sides of lengths $a$, $b$, and $c$,
and angles $\alpha$, $\beta$ and $\gamma$ opposite these three sides,
we have the following:
The Law of Sines:
$$ \frac{\sin(\alpha)}{a}=\frac{\sin(\beta)}{b}=\frac{\sin(\gamma)}{c}$$
The Law of Cosines:
$$c^2=a^2+b^2 -2ab\cos(\gamma)$$
