1. The problem asks to find the value of the ratio $\frac{\alpha}{\beta}$ given the angles $\alpha$ and $\beta$ in a geometric figure. 2. Since the figure is a quadrilateral with a diagonal, and angles $\alpha$ and $\beta$ are at the bottom side, we can use angle relationships in polygons. 3. The sum of angles on a straight line is $180^\circ$, so if $\alpha$ and $\beta$ are adjacent angles on the bottom side, then $\alpha + \beta = 180^\circ$. 4. To find $\frac{\alpha}{\beta}$, express $\alpha$ as $180^\circ - \beta$ and substitute: $$\frac{\alpha}{\beta} = \frac{180^\circ - \beta}{\beta} = \frac{180^\circ}{\beta} - 1$$ 5. Without a specific value for $\beta$, the ratio depends on $\beta$. If $\beta$ is known, substitute to get a numeric ratio. 6. If the problem implies $\alpha = \beta$ (e.g., by symmetry), then: $$\frac{\alpha}{\beta} = 1$$ 7. Otherwise, the ratio is $\frac{180^\circ}{\beta} - 1$. Since no numeric values are given, the ratio is expressed in terms of $\beta$. Final answer: $$\boxed{\frac{\alpha}{\beta} = \frac{180^\circ}{\beta} - 1}$$
