Math rules and equations.

I'm trying to work out some dimensions, and I've forgotten all the rules that we learnt in high school since I haven't needed to use them since.

That's the picture with the diagram

I'm trying to work out the angles for a, b, c, and the length of d. I am also trying to work out the area.

Could someone please give me a hand... If you tell me the answers I'll hit you with a halfbrick in a sock. Just the equations please.

cos a = (1,3) / (2,3) -- (1,3) = line from 1 to 3
