Good Afternoon everyone, First and foremost Id like to say Thank you in advance for any help I may receive. I am new to this forum and I typically ask questions when all else fails..well friends, all else failed

I am writting some code in visual studio (unrelated), but I have to put in a formula that will give me the tangent points of a circle, A chord in the circle and another circle thats tangent to the chord and the circle. So I have a big circle with a chord that runs right thru it. I know the center in (X,Y) of the Big Circle, and I know the Chord Length. I then have another circle that is Tangent to the big Circle and the Chord line. But, I only know the Y center of that circle and ofcourse Diameter. Im trying to find the tangent points.. I hope someone can guide me to the right direction. I have included a screen shot of what I am talking about. If I need to give more info. Please tell me. I will forever appreciate the help. Thank you so much again..
