![## Problem Statement:
Let \( \sin A = \frac{3}{5} \) with \( A \) in Quadrant II and \( \sin B = -\frac{8}{17} \) with \( B \) in Quadrant III. Find \( \sin(A + B) \), \( \cos(A + B) \), and \( \tan(A + B) \).
### Formulae:
1. \( \sin(A + B) = \sin A \cos B + \cos A \sin B \)
2. \( \cos(A + B) = \cos A \cos B - \sin A \sin B \)
3. \( \tan(A + B) = \frac{\tan A + \tan B}{1 - \tan A \tan B} \)
### Given Values:
- \( \sin A = \frac{3}{5} \)
- \( \sin B = -\frac{8}{17} \)
### Required:
- \( \sin(A + B) \)
- \( \cos(A + B) \)
- \( \tan(A + B) \)
## Solution:
Make sure to consider the right signs for the trigonometric functions in their respective quadrants.
### Incorrect Answers Indicated:
- \( \sin(A + B) = \) ❌
- \( \cos(A + B) = \) ❌
