Final Answer:
The numerical representation of a 90° CCW rotation is 270. Option C is answer.
Step-by-step explanation:
A 90° CCW rotation is equivalent to rotating an object 90 degrees to the left. In numerical terms, this means adding 270 to the original angle. Therefore, the answer is 270.
The other options are incorrect:
180 represents a 180° rotation, which is equivalent to rotating an object upside down.
360 represents a full circle, which is equivalent to rotating an object 360 degrees back to its original position.
90 represents a 90° CW (clockwise) rotation, which is equivalent to rotating an object 90 degrees to the right.
Option C is answer.
