The point A, B,C and D represent the complex number Z1,Z2,Z3 and Z4 and O is the origin. If OABC is a parallelogram, and Z1=1+3i and Z2=4+5i, find Z3

Complex numbers are divided into two parts; real and imaginary parts. The value of Z3 is

Given that:

Since O is the origin, then:

This means that:

So, we have:

Collect like terms

Hence, complex number Z3 is
