It’s 54 degrees because all the angles are the same
Anyways the center will be (-9;6)
The answer is d.
to find the slope you can do y2-y1/x2-x1
8-(-1)/3-0= 9/3 or 3
you can then put one of the points into the slope intercept form y=mx+b or 8=3(3)+b
you get 8=9+b. you subtract 9 from both sides to get -1=b. y intercept means that the point is (0,-1)
