Math

Using the rule about the sides of a triangle, where the sum of any two sides must be greather than the third. 

We have these inequalities:

7 + 3 > x

7 + x > 3

x + 3 > 7

Simplifying these inequalities, we have:

x < 10

x > -4

x > 4

The possible integer lengths are:

5, 6, 7, 8, and 9.

I hope this helped,

Solution:

a^2+b^2=c^2

So, 7^2+3^2=c^2

m^2=58

m=7.61- 8

7+3>m

m<10

So, 5,6,7,,8,9
