Answer:
C
Step-by-step 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.
