**Title: Calculating the Length of a Triangle Side Using the Law of Cosines**

**Problem Statement:**

Consider the triangle shown below where \( \angle C = 53^\circ \), \( b = 10 \text{ cm} \), and \( a = 24 \text{ cm} \). 

**Diagram Description:**

- The triangle is labeled with points \( A \), \( B \), and \( C \).
- Angle \( \angle C \) is \( 53^\circ \).
- Side \( AC \) is \( 10 \text{ cm} \).
- Side \( BC \) is \( 24 \text{ cm} \).
- Side \( AB \) is \( x \) cm (to be determined).

**Instructions:**

1. Substitute the given values into the Law of Cosines formula:
\[ x^2 = a^2 + b^2 - 2ab \cos(C) \]

2. Given:
   - \( a = 24 \text{ cm} \)
   - \( b = 10 \text{ cm} \)
   - \( \angle C = 53^\circ \)

3. Calculate the value of \( x \):
\[ x = \sqrt{24^2 + 10^2 - 2 \cdot 24 \cdot 10 \cdot \cos(53^\circ)} \]

4. Enter your value for \( x \) in the provided input box and click "Preview" to check your answer.

5. Once reviewed, click "Submit" to finalize your answer.
