Question
**Problem Statement:**

The triangle below is equilateral. Find the length of side \( x \) in simplest radical form with a rational denominator.

**Diagram Explanation:**

- The diagram shows an equilateral triangle with a side length divided by an altitude.
- The altitude forms two 30-60-90 right triangles within the equilateral triangle.
- The length given along the altitude is 5.
- The segment of the side length opposite the 30-degree angle (half of one side of the equilateral triangle) is denoted as \( x \).
- The right angle is marked near the vertex connecting the altitude and the base.

**Answer Choices:**

Below the diagram are multiple-choice answers to the problem statement:

- \( \frac{5\sqrt{3}}{3} \) (selected answer)
- \( 5\sqrt{2} \)
- \( \frac{5\sqrt{2}}{2} \)
- 2.5
