and to add to that
does anyone know the cosine rule for angles???

yes, SinA/a = SinB/b, where A is an angle and a is a length of a triangle
this may help: https://www.youtube.com/watch?v=RL2F49BwQTA

Sine rule for angles is Sin(A)/a=Sin(B)/b
Cosine rule for angles is Cos(A) =b2 + c2 - a2/2bc Therefore A = Cos-1(b2 + c2 - a2/2bc)
Cosine rule for angles is Cos(A) =b2 + c2 - a2/2bc Therefore A = Cos-1(b2 + c2 - a2/2bc)

im guessing u just rearranged the formula right
thanks
