Problem
The sides of a triangle have lengths 
, 
, and 
, where is a whole number. What is the smallest possible value of ?
![[asy] pair A,B,C; A=origin; B=(10,0); C=6.5*dir(15); dot(A); dot(B); dot(C); draw(B--A--C); draw(B--C,dashed); label("$6.5$",3.25*dir(15),NNW); label("$10$",(5,0),S); label("$s$",(8,1),NE); [/asy]](http://latex.artofproblemsolving.com/c/9/2/c92ca742ef1e1c4b45c953991f78ff1e6bc82f1a.png)
