Answer 1

C

Explanation:

Remember that counter-clockwise angles are positive while clockwise angles are negative.

In other words, since we are doing a counter-clockwise rotation, our answer should be a positive value. Hence, we can eliminate A and B.

Recall that each rotation is equivalent to 360°.

So, one-half of a rotation is equivalent to 180°.

Therefore, a 1.5 rotation is equivalent to 360° + 180° = 540°.

And since our angle must be positive, our answer is 540°.

C is the correct choice.
