Have a bit of a puzzle for the mathematical minded person

I need the lengths of b to c and a to c and just cant get my head in gear....... :oops: :oops:

I have used more than 1 method and confused myself...... :doh: :doh:



The numbers in the corners are degrees 8-[

Also no longer got a Zeus book  :-.

Calculate AC

                     Sin C = Opp/Hyp
                     Sin 42 = 3050/AC
                     AC = 3050/Sin 42
                     AC = 4558.15

Calculate BC

                    Tan A = Opp/Adj
                    Tan 48 = BC/3050
                    BC = Tan 48*3050
                    BC = 3387.37

Hope that helps

Oh and for future reference

Thanks Mikie  :clap:
