A triangle has 2 side lengths 8 and 10 what value could the length of the third side be

2 < x < 18

Step-by-step explanation:

The sum of the shorter two sides of a triangle must be greater than the longest side.

If 10 is the longest side:

x + 8 > 10

x > 2

If x is the longest side:

8 + 10 > x

18 > x

The length of the third side must be greater than 2 and less than 18.
