1. **State the problem:** We need to find the equation of a line $L$ that passes through the point $(3, -2)$ and is inclined at an angle of $60^\circ$ to the line $\sqrt{3}x + y = 1$. The line $L$ also intersects the x-axis.
2. **Find the slope of the given line:** The given line is $\sqrt{3}x + y = 1$. Rewrite it in slope-intercept form:
$$y = -\sqrt{3}x + 1$$
So, the slope of this line is $m_1 = -\sqrt{3}$.
3. **Use the angle between two lines formula:** If $m_1$ and $m_2$ are slopes of two lines inclined at an angle $\theta$, then
$$\tan \theta = \left| \frac{m_1 - m_2}{1 + m_1 m_2} \right|$$
Given $\theta = 60^\circ$, so $\tan 60^\circ = \sqrt{3}$.
4. **Set up the equation for $m_2$:**
$$\sqrt{3} = \left| \frac{-\sqrt{3} - m_2}{1 - \sqrt{3} m_2} \right|$$
5. **Solve for $m_2$:** Consider the positive case:
$$\sqrt{3} = \frac{-\sqrt{3} - m_2}{1 - \sqrt{3} m_2}$$
Multiply both sides by denominator:
$$\sqrt{3}(1 - \sqrt{3} m_2) = -\sqrt{3} - m_2$$
$$\sqrt{3} - 3 m_2 = -\sqrt{3} - m_2$$
Bring all terms to one side:
$$\sqrt{3} + \sqrt{3} = - m_2 + 3 m_2$$
$$2 \sqrt{3} = 2 m_2$$
$$m_2 = \sqrt{3}$$
6. **Check the negative case:**
$$\sqrt{3} = - \frac{-\sqrt{3} - m_2}{1 - \sqrt{3} m_2} = \frac{\sqrt{3} + m_2}{1 - \sqrt{3} m_2}$$
Multiply both sides:
$$\sqrt{3}(1 - \sqrt{3} m_2) = \sqrt{3} + m_2$$
$$\sqrt{3} - 3 m_2 = \sqrt{3} + m_2$$
$$-3 m_2 - m_2 = \sqrt{3} - \sqrt{3}$$
$$-4 m_2 = 0$$
$$m_2 = 0$$
7. **Possible slopes for line $L$ are $m_2 = \sqrt{3}$ or $m_2 = 0$.**
8. **Find the equation of line $L$ passing through $(3, -2)$ with slope $m_2$:**
- For $m_2 = \sqrt{3}$:
$$y - (-2) = \sqrt{3}(x - 3)$$
$$y + 2 = \sqrt{3} x - 3 \sqrt{3}$$
$$y = \sqrt{3} x - 3 \sqrt{3} - 2$$
- For $m_2 = 0$:
$$y - (-2) = 0(x - 3)$$
$$y + 2 = 0$$
$$y = -2$$
9. **Check which line intersects the x-axis:**
- For $y = \sqrt{3} x - 3 \sqrt{3} - 2$, set $y=0$:
$$0 = \sqrt{3} x - 3 \sqrt{3} - 2$$
$$\sqrt{3} x = 3 \sqrt{3} + 2$$
$$x = 3 + \frac{2}{\sqrt{3}}$$
This is a valid intersection.
- For $y = -2$, the line is parallel to x-axis and does not intersect it.
10. **Final answer:** The equation of line $L$ is
$$y = \sqrt{3} x - 3 \sqrt{3} - 2$$
