1. Problem Description

The problem asks for the center of a circle with the given equation (x5)2+(y+8)2=36(x - 5)^2 + (y + 8)^2 = 36.

2. Solution Steps

The standard form of the equation of a circle with center (h,k)(h, k) and radius rr is given by:
(xh)2+(yk)2=r2(x - h)^2 + (y - k)^2 = r^2.
Comparing this with the given equation (x5)2+(y+8)2=36(x - 5)^2 + (y + 8)^2 = 36, we can identify the center and the radius.
We have (xh)2=(x5)2(x - h)^2 = (x - 5)^2, so h=5h = 5.
We also have (yk)2=(y+8)2(y - k)^2 = (y + 8)^2. Since y+8=yky + 8 = y - k, we have k=8k = -8.
Therefore, the center of the circle is (5,8)(5, -8).

3. Final Answer

The center of the circle is (5,8)(5, -8).
