## Trigonometry Problem

### Given Information:
- \( y = 5 \) cm
- \( Y = 0.1 \) radians
- \( X = 1.4 \) radians

### Objective:
Determine the following quantities:
1. \( Z \) (angle in radians)
2. \( x \) (side length in cm)
3. \( z \) (side length in cm)

### Diagram Explanation:
The image depicts a triangle labeled with angles and sides as follows:
- The angle at the top vertex is labeled \( Y \).
- The angle at the bottom left vertex is labeled \( X \).
- The angle at the bottom right vertex is labeled \( Z \).
- The side opposite to angle \( X \) is labeled \( x \).
- The side opposite to angle \( Y \) is labeled \( y = 5 \) cm.
- The side opposite to angle \( Z \) is labeled \( z \).

### Tip:
Draw your own picture and label it carefully. You may find it useful to use trigonometric identities, the Law of Sines, and/or the Law of Cosines to solve for the unknown quantities.

### Calculations:

\[ \text{Z } = \text{(in radians)} \quad \text{ [Preview]} \]
\[ \text{x } = \text{(in cm)} \quad \text{ [Preview]} \]
\[ \text{z } = \text{(in cm)} \quad \text{ [Preview]} \]

Solve for \( Z \), \( x \), and \( z \) using the given measurements and appropriate trigonometric laws. Ensure the correct application of trigonometric identities, considering the radians provided for angles \( X \) and \( Y \).
