Question 1160102

given: two sides are {{{18}}} and {{{13}}}

third side {{{x}}}  must be less then their sum:

{{{x < 18+13}}}

{{{x< 31}}}.......since we need side length, exclude negative numbers and {{{0}}}

{{{x}}}={{{1}}},{{{2}}}, {{{3}}},........{{{30}}}

since one side {{{18}}}  must be also less then the sum of {{{13}}} and {{{x}}}, 

 {{{18<13+x}}}
{{{18-13<x}}}
{{{x>5}}}

first whole number greater than {{{5}}} is {{{6}}}

so, the smallest possible whole number length for the third side is {{{6}}}
