If you really mean a radius tangent to two circles, it's Circle - Tangential Two Circles, Radius. Cut open the r 105 circle at the tangent points (snap intersection on) and delete the unwanted part.
But in the picture it looks like the 105 radius instead intersects with the upper left circle at it's left quadrant. Something different, I don't know a solution for that.
