$begingroup$


In the triangle shown, for $angle A$ to be the largest angle of the triangle, it must be that $m<x<n$. What is the least possible value of $n-m$, expressed as a common fraction? The diagram of the triangle

          $x+9$ must be the largest side. But it must also be less than the sum of the other two sides, by triangular inequality.
