Answer:

180°

Step-by-step explanation:

The reflection of a point (x,y) by 180° yields a point (-x,-y). That is, the coordinates are multiplied by -1. So, The point Y with coordinates (-9,5) rotated counterclockwise about the origin to Y'(9,-5) is rotated by 180° since, the coordinates are multiplied by -1.
