Notice that this is in the third quadrant.
Its length is
The angle is in the third quadrant.
So it's calculated as
First you need to convert to polars.
Notice that the angle is in the fourth quadrant.
So it's calculated by

is just a shorthand way of writing .
As we know, .
So I could have written , I just prefer using the notation, as I find it easier to convert between polars and cartesians.
