### Exploring the Concepts
In problems involving trigonometry, such as the ones above, it is crucial to accurately understand the relationships between angles and side lengths. Triangles, particularly right triangles, frequently use trigonometric ratios (sine, cosine, tangent) to relate angles to side lengths. When solving these problems, recognize angle characteristics and apply appropriate functions.
**Key Concepts to Recall**:
- Trigonometric Ratios: \( \sin(\theta) = \frac{\text{opposite}}{\text{hypotenuse}} \), \( \cos(\theta) = \frac{\text{adjacent}}{\text{hypotenuse}} \), \( \tan(\theta) = \frac{\text{opposite}}{\text{adjacent}} \)
- Special Right Triangles: For instance, 45°-45°-90° and 30°-60°-90° triangles have consistent side ratios.
