1. **State the problem:** We have a right triangle with angles 30°, 60°, and 90°. The side opposite the 60° angle is 1 meter, and we need to find the side $k$ opposite the 30° angle.
2. **Recall the special right triangle ratios:** In a 30°-60°-90° triangle, the sides are in the ratio:
$$1 : \sqrt{3} : 2$$
where 1 is the side opposite 30°, $\sqrt{3}$ opposite 60°, and 2 is the hypotenuse.
3. **Identify given side:** The side opposite 60° is given as 1 meter. According to the ratio, this side corresponds to $\sqrt{3}$ units.
4. **Set up proportion:** Let the common factor be $x$. Then:
$$x \sqrt{3} = 1$$
5. **Solve for $x$:**
$$x = \frac{1}{\sqrt{3}}$$
6. **Find $k$, the side opposite 30°:**
$$k = x \times 1 = \frac{1}{\sqrt{3}}$$
7. **Simplify $k$ to simplest radical form:**
$$k = \frac{1}{\sqrt{3}} \times \frac{\sqrt{3}}{\sqrt{3}} = \frac{\sqrt{3}}{3}$$
**Final answer:**
$$k = \frac{\sqrt{3}}{3} \text{ meters}$$
