To determine if two angles are adjacent, we need to know that adjacent angles share a common vertex and a common ray. Based on the options provided:
C. Yes, they share a common ray.
This choice would be accurate if both angles indeed have a common vertex and share one ray. If this is not the case, then the correct option would depend on the specific situation.
If you can provide a diagram or more details about the angles in question, I can give a clearer answer. But typically, adjacent angles do share both a common vertex and a common ray.
