Question

A triangle has two sides of length 9 and 14 what is the smallest possible whole number length for the third side

Answer 1

Let the third side = x.

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

14 + 9 > x

  23 > x

14 + x > 9

   x > -5

9 + x > 14

   x > 5

So 5 < x < 23
