**Reiny**, Monday, October 1, 2012 at 9:20pmlet the third side be x

The sum of any two sides must be greater than the third side

x+14 > 10 or

x > -4, but x must be positive, so x> 0 DUHH!

AND

x+10 > 14

x > 4

AND

10+14 > x

x < 14 --------> 4 < x < 14

so x has to be 5, 6, 7 , .... 13

I count 9
