Answer:
- thirteen pi divided by six (positive)
- negative eleven pi divided by six (negative)
Step-by-step explanation:
The co-terminal angles are ...
- thirteen pi divided by six (positive)
- pi divided by six + 360° (positive)
- pi divided by six - 360° (negative)
- negative eleven pi divided by six (negative)
We usually don't like to mix degrees and radians, so the above answer selects a positive and negative angle that doesn't do that.
