Andy the Ant lives on a coordinate plane and is currently at (−20,20)(-20, 20) facing east (that is, in the positive xx -direction). Andy moves 11 unit and then turns 90∘90^{\circ} left. From there, Andy moves 22 units (north) and then turns 90∘90^{\circ} left. He then moves 33 units (west) and again turns 90∘90^{\circ} left. Andy continues his progress, increasing his distance each time by 11 unit and always turning left. What is the location of the point which Andy makes the 20202020 left turn?
