[ Algebraic problems on the triangle inequality ]

In a triangle, two sides are equal to 3.14 and 0.67. Find the third side, given that its length is an integer.

#
Apply the triangle inequality.

## Solution

Let the integer $n-$ be the length of the third side. Then

$$
3.14-0.67<n<3.14+0.67
$$

From this, we find that $n=3$.

## Answer

3.
