  • It's very long so I'm not giving answers but here's how i would do it:
  1. use Pythagoras [tex]a^2 +b^2 = c^2[/tex] where c is the longest side
  2. use sine rule [tex]\frac{a}{sin(A)} = \frac{b}{sin(B)} = \frac{c}{sin(C)}[/tex] where lower cases are the sides, and capitals are their opposite angles.

e.g for 15:

a = 3, b is missing, c = 10

A is missing, B is ?, C is 90
