Last part.
For the first three parts, perhaps J or Boy Mow Chau may have a better thought on this. I have a rough idea for the first two parts geometrically, but have no idea on how to put them in complex form.

This negative result would make the triangle become labelled clockwise instead.
(c - i)² = (3√3 + 4√3 i)²
(c - i)² = (3√3 + (4√3 + 1)i - i)²
Comparing coefficients,
c = 3√3 + (4√3 + 1)i
