Poem

Brotherhood
Can be so good
Together in life
Without boundaries
Without wars
Just seeking for peace
Sharing emotions
Feelings are growing
On every face
Let’s built together
A new world

You did not desert me
My Brothers in arms”

Well, the solution is a/b considering that the segment which contains b is also tangent to the other point of contact. It might sound obvious but in the problem that was not very clear.
