Hello,

Isn't it w=(-9*sqrt(2))/2 + (9*sqrt(2))/2 i ?

First of all, multiply above and below by the conjugate of wdetermine z/w in polar form

I think this would come laterCould some one please get me started I dont know how you can find the angle formed when z=5i?

Try to get to the step I mentioned.

If you have z=5i, it means that z=0+5idont I need a real part not just imaginary

So we can see that and
