Question28. Use the figure to answer questions $a$ and $b$. a. Are the triangles above similar? Explain. b. If possible, find the missing side length, $x$.

Studdy Solution
Solve the proportion for $x$: $$\frac{48}{12} = \frac{12}{x}$$ $$4 = \frac{12}{x}$$
Cross-multiply to solve for $x$: $$4x = 12$$ $$x = \frac{12}{4}$$ $$x = 3$$
The missing side length $x$ is:
$$\boxed{3}$$
