Point A: (11,8)

Therefore Center of Circle = (2,-1) and Radius = 5

Looks somewhat like:

Basically there are two tangents coming from the edge of a circle with the above equation to a point (pt. A). I have figured out to make two right triangles by putting a line between the center point of a circle to pt. A. I then got the distance between the center point and point A using the distance formula. Distance = 12.7279. Using the Pythagoras rule I solved each right triangle to get that the length of each tangent is 11.7047. I need to get the points though that connect the radii and tangents to the circle, so that I can get the slope of each tangent and write the equation for each tangent line. I'm unsure of how to do this, so can someone please help? Thanks.
