Sorry but i dont know the right answer
Answer:

Step-by-step explanation:
Equation of circle is
Where (a, b) is center of circle and r is radius
Here (a, b) = (6, -3) and radius can be determined by calculating the distance from center to point (1, 1)

Substituting values in equation of circle

It is therefore unknown since there is no graph and/or diagram. I do say that the angle is whatever the correct answer is
