does anyone know the sine rule for angles???
and to add to that
does anyone know the cosine rule for angles???
you have literally saved me
because I doing an exam practice paper for my maths revision
and I was panicking
I wouldn't call it revision though as Im asking for help
well that's just me LOL
Cosine rule for angles is Cos(A) =b2 + c2 - a2/2bc Therefore A = Cos-1(b2 + c2 - a2/2bc)
