Hello!
The equation for a circle is

(h,k) is the center
r is the radius
Put in the values you know

Simplify

The equation is

Hope this helps!
If two tangent segments to a circle share a
common endpoint outside a circle, then the two segments are congruent. This
is according to the intersection of two tangent theorem. The theorem states
that given a circle, if X is any point
within outside the circle and if Y and Z are points such that XY and XZ are
tangents to the circle, then XY is equal to XZ.
