Answer:
8 units, 15 units, 17 units
Step-by-step explanation:
A triangle can only be considered a right triangle if it satisfies the Pythagorean Theorem.
Case 1 : Side lengths 8, 9, 15
- 8² + 9² = 15²
- 64 + 81 = 225
- 145 ≠ 225
- Not satisfied
Case 2 : Side lengths 8, 15, 17
- 8² + 15² = 17²
- 64 + 225 = 289
- 289 = 289
- Satisfies condition
Therefore, she should use the side lengths 8 units, 15 units, 17 units, as it forms a right triangle.
