1. **State the problem:** We have a right triangle with sides labeled 5, 6, $y-1$, $x-2$, and 10, and we want to find the unknown values $x$ and $y$ using proportions.
2. **Set up proportions:** In similar triangles or right triangles with altitudes, corresponding sides are proportional. The problem suggests using the given side lengths to write proportions.
3. **Write the proportions:** From the diagram and labels, the proportions are:
$$\frac{5}{y-1} = \frac{6}{10}$$
and
$$\frac{x-2}{5} = \frac{6}{10}$$
4. **Solve for $y$:**
Multiply both sides of the first proportion by $y-1$:
$$5 = \frac{6}{10} (y-1)$$
Multiply both sides by 10 to clear the denominator:
$$10 \times 5 = 6 (y-1)$$
$$50 = 6 (y-1)$$
Divide both sides by 6:
$$\frac{50}{6} = y-1$$
Simplify fraction:
$$\frac{50}{6} = \frac{25}{3} \approx 8.333$$
Add 1 to both sides:
$$y = 8.333 + 1 = 9.333$$
5. **Solve for $x$:**
Multiply both sides of the second proportion by 5:
$$x-2 = \frac{6}{10} \times 5$$
Simplify right side:
$$x-2 = 3$$
Add 2 to both sides:
$$x = 5$$
**Final answers:**
$$x = 5, \quad y \approx 9.333$$
