Example A-7.2

 Two sides of a triangle have lengths a = 5 and b = 2 and the angle between them is $C=52°$. Use the Law of Sines and the Law of Cosines to find the other side c and the other two angles A and B opposite a and b, respectively.

 Law of Sines: $\frac{\mathrm{sin}\left(A\right)}{a}=\frac{\mathrm{sin}\left(B\right)}{b}=\frac{\mathrm{sin}\left(C\right)}{c}$ Law of Cosines:
