Hey Guys, I have a trigonometry question

The game is setup around a circle, the player rotates around the circle, and the player can jump of the circle before landing back on it. The goal would be for the player to jump straight out, so what I would need to know is what degrees he would be jumping towards. Oblivious it is easy at the Axis points, 90, 360, 270, 0. But how would I mathematically find what degrees that character would be jumping towards somewhere in the middle? How would I do this with a formula

I am assuming I will use Atan2 or something similar for this I am just not entirely sure how to do it:(

I made a small diagram of what I am trying to explain if I was unclear, the arrow represents the circle shooting straight out...
