D. Inscribed angle
<h2>Step-by-step explanation:</h2>An inscribed angle has a vertex on the circumference. For any arc, every inscribed angle is exactly half of the central angle. In other words, if the central angle is and the inscribed angles is
, then it is true that:
In this problem , then the central angle is
The equation for a circle is as followed:
where the center of the circle is at (h,k) and the radius of the circle is r.
We are given (h,k) and need to find the radius. To do so, we can use the distance formula to find the distance from the center to the point on the circle:
Plug in the two points:
If the distance from the center to the edge of the circle is the square root of 117, then r^2 = 117.
