**Steve**, Thursday, June 21, 2012 at 3:45pmany side of a triangle is less than the sum of the other two sides. So, if x is the missing side,

5 < x+3

2 < x

so, x must be at least 2.

Similarly, there is a maximum value for x, since we must also have

x < 5+3

x < 8

since, even stretching out the other two sides end to end, they couldn't reach farther than 8.
