Question 335191
Let A,B,C be the sides from shortest to longest.
{{{B=A+1}}}
{{{A=B-1}}}
.
.
.
{{{B=C-1}}}
{{{C=B+1}}}
.
.
.
{{{A+B+C=17}}}
Substitute the above values and solve for B.
{{{(B-1)+B+(B+1)=17}}}
{{{3B=17}}}
{{{highlight( B=17/3)}}}
.
.
.
{{{A=17/3-3/3}}}
{{{highlight(A=14/3)}}}
.
.
.
{{{C=17/3+3/3}}}
{{{highlight(C=20/3)}}}
