As written, there are an infinite number of solutions to this problem;
one is the circle with its center at the point common to the two lines 
and with a radius of the 'known distance.'

Even if you specify that 'touches' means 'is tangent to,' there are an
infinite number of solutions.  Do you mean one that is tangent to both
lines?
