.
The question in this post is about the length of the common INTERIOR tangent to two non-overlying circles.
I don't know (don't sure) if @Matlower have read the problem and the question, at all,
but she answered OTHER question about the length of the common EXTERIOR tangent to two cirles.
So, her answer/solution is NOT RELEVANT to the problem.
THEREFORE, I came to give you the link (the reference) to the real source.
See the lesson
- HOW TO construct a common interior tangent line to two circles
in this site.
The problem 2 of this lesson contains the solution to your problem.
Learn it from there.
