Possible values of third side would be in the interval $(2,8)$ , not including $2$ and $8$ .

If $3$ and $5$ are two sides of a triangle, the third side say $x$ , will be such that $x<8$ .

Further, if i is smallest side of triangle, we will have $5<3+x$ i.e. $x>2$

Hence, possible values of third side would be in the interval $(2,8)$ , not including $2$ and $8$ .

If two sides of a triangle are 33 and 55, in what interval can we have the third side?
