2 sides of a triangle are 5.2 and 3.1 what is the 3rd side
Let's call the unknown third side of the triangle "x". According to the triangle inequality theorem, the sum of the lengths of any two sides of a triangle must be greater than the length of the third side.
Given that the two sides of the triangle are 5.2 and 3.1, we have:
5.2 + 3.1 > x
8.3 > x
Therefore, the third side of the triangle must be less than 8.3.
