    Complex numbers and Argan Diagram

    Hi, I desperately need help with this qns: In an Argan Diagram, the points A, B, C, D represent the copmlex numbers a,b,c,d respectively. Guiven that ABCD is a rectangle describd in an anticlocwise sense, with AB=2CB, and a=-2-i, c=3+5i, find b and d (AB and CD are not parallel to the xaxis)...
