I assume this is a triangle and 2.8 is the length of two sides of the triangle.

Considering the Triangle Inequality Theorem, that states that the sum of any 2 sides of a triangle must be greater than the measure of the third side, the possible lenght of the third side is:

2.8-2.8 < x < 2.8+2.8

0 < x < 5.6
