For a triangle, the sum of any two sides should be greater than the third side. The difference between the two sides of the triangle should be less than the third side.
The given sides of a triangle are 12 and 5.
Let x be the length of third side.
[tex]12-5=7Therefore, the possible values of x is between 17 and 7.
Therefore, the length of the third side x can be 8, 9, 10, 11, 12, 13, 14, 15 or 16.
