I need some help with converting this to cartesian form.(adsbygoogle = window.adsbygoogle || []).push({});

z=-1+1i

On a graph the relation is (-1,1)

Then I use the pythagorean theorem to find the hypotenuse which works out to be the square root of 2. How do I then find what the angle of the triangle is using the unit circle?
