Move Direction Help

Top View

I am trying to get the brush to move in that direction but I cannot figure out what the degree for it to move that way would be.

90 I think

no i tried that. that just moves it up.
It needs to go in the direction across from it

The move direction should be zero to move that way.

oh duh lol
I kept thinking 0 would mean it would not move

Select and drag that little circle in that direction in which you want your brush to move.
