I wasn't think of this in the plane but you can use the 1 in 60 rule. By looking at my distance from the fix on the GPS along with the radial to it I could have calculated at 175nm(where i was initially) to 60nm(where I wanted to go on the fix. 175nm-60nm=115nm difference. Take the radial on the GPS and take difference between it and the radial I'm flying to.

If this is what he's talking about. Of course I'm guessing it's not legal. Though I don't think doing it his way is either lol.

Anyway I got my answer. I'm done here. Thanks I think.
