The image shows a geometry problem involving two triangles, one inscribed within the other, and asks to find the lengths of segments \( BC \) and \( AC \) using similar triangles.

We are given the following information from the image:
- The right-angled triangle \( ABC \) and another triangle \( AXY \).
- Segment \( AB = 5 \, \text{cm} \), segment \( BX = 8 \, \text{cm} \), segment \( AX = 6 \, \text{cm} \), and segment \( XY = 10 \, \text{cm} \).

We will use the concept of similar triangles. The triangles \( ABC \) and \( AXY \) appear to be similar because they share an angle (at \( A \)) and both have right angles, implying angle-angle similarity.

### Step 1: Set up the ratio of corresponding sides
For similar triangles, the ratios of corresponding sides are equal. So, we have:

\[
\frac{AB}{AX} = \frac{BC}{XY}
\]

Substitute the given values:

\[
\frac{5}{6} = \frac{BC}{10}
\]

### Step 2: Solve for \( BC \)
We now solve for \( BC \) by cross-multiplying:

\[
BC = \frac{5}{6} \times 10 = \frac{50}{6} = 8.33 \, \text{cm}
\]

### Step 3: Solve for \( AC \)
Similarly, the ratio for the hypotenuses of the triangles is:

\[
\frac{AC}{AY} = \frac{AB}{AX}
\]

Since \( AY = XY \) (they are the same length):

\[
\frac{AC}{10} = \frac{5}{6}
\]

Solving for \( AC \):

\[
AC = \frac{5}{6} \times 10 = 8.33 \, \text{cm}
\]

### Conclusion:
- The length of \( BC \) is approximately \( 8.33 \, \text{cm} \).
- The length of \( AC \) is also approximately \( 8.33 \, \text{cm} \).
