### Vector Scalar Product Calculation

#### Problem Statement

**Vector \( \vec{A} \)**:
- Length: 24.4 units
- Direction: Along the x-axis

**Vector \( \vec{B} \)**:
- Length: 24.3 units
- Direction: 123° counter-clockwise from the x-axis

#### Task
Calculate the scalar product (dot product) \( \vec{A} \cdot \vec{B} \).

#### Answer Input
- [Your Answer: _______]

### Explanation

To calculate the scalar product \( \vec{A} \cdot \vec{B} \), we use the formula:

\[ \vec{A} \cdot \vec{B} = |\vec{A}| |\vec{B}| \cos(\theta) \]

where:
- \( |\vec{A}| \) is the magnitude of vector \( \vec{A} \)
- \( |\vec{B}| \) is the magnitude of vector \( \vec{B} \)
- \( \theta \) is the angle between the vectors \( \vec{A} \) and \( \vec{B} \)

Given values:
- \( |\vec{A}| = 24.4 \)
- \( |\vec{B}| = 24.3 \)
- \( \theta = 123^\circ \)

Next, calculate the cosine of the angle:
\[ \cos(123^\circ) \]

Finally, plug the values into the formula to find the scalar product.
