- Pythagoras theorem, inverse tan function

So i found the magnitude which is

(-1)^2 + (-2)^2 = P^2 =

Sqrt(5)

**Then I used the inverse tan function to find the angle (direction)**

theta = arctan (-2/-1) = 63.8 degrees

Im confused with my 63.8 degrees since the angle in the graph looks greater than 63.4 degrees

I subtracted 180 by 63.8 and got 116.6

Since it's going clock wise it's -116.6

Am i right?
