Please I really need your help. I do not know how to do this problem.

- Math,Geometry -
**Anonymous**, Monday, January 7, 2013 at 7:08pmyou are looking for two of the radii of the circle (x+5)^2 + (y+3)^2 = r^2

r^2 equals the square of the distance from (-5,-3) to (5,7), minus (2√5)^2

the radii are tangent to

(x-5)^2 + (y-7)^2 = 20

the points of tangency (intersections of the two circles) will give the points needed (along with (-5,-3))to write the equations of the lines
