Answer:
Center (4, -13)
Radius = 17
Step-by-step explanation:
Circle equation:
(h, k) is the center of the circle and the r is the radius.
h = 4, k = -13, r = 17
In the unit circle the hypotenuse of the triangle formed is equal to radius of circle , which = 1. The point on the circle formed by the intersection of the hypotenuse is (cos q , sin q) where q is the angle between the x axis and the hypotenuse. As the hypotenuse = 1 the opposite and adjacent sides of the triangle < 1 so sin and cos of q must both be <= 1.
