    Unhappy Help for Solution of a Circle tangent to another circle and a line. (picture incl)

    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..

    Re: Help for Solution of a Circle tangent to another circle and a line. (picture incl

    Ok so I figured it out after playing with it. I was able to get X by Figuring the hypotenuse, which is R1 Big radius minus R2 small radius. Then since my Y is already known, I was able to find my intersection points easily by triging my way around it. Just thought Id post incase someone, someday has the same questions.. Thanks for viewing..
