Let a = 4 + 3i, b = 1 -2i, and c = 8 - 5i. The complex number d is such that a,b, c, and d form the vertices of a parallelogram, when plotted in the complex plane. Enter all possible values of d, separated by commas.
Can I also have a solution? I need help asap. If you know how to do it, can you please help me? Thanks.
+36916 Easiest to look at it on a graph then 11+0i and 5 - 10 i look to be solutions
