To determine which triangle has an unknown side length of \(\sqrt{37}\) units, we can apply the triangle inequality theorem. The theorem states that for any triangle with sides \(a\), \(b\), and \(c\), the following inequalities must hold:
1. \(a + b > c\)
2. \(a + c > b\)
3. \(b + c > a\)
We'll evaluate each option to check if \(\sqrt{37}\) can be an unknown side while satisfying the triangle inequality.
1. **Option 1:** Sides are \(4\), \(\sqrt{2}\), and \(\sqrt{37}\)
- \(4 + \sqrt{2} > \sqrt{37}\)
- \(4 + \sqrt{37} > \sqrt{2}\)
- \(\sqrt{2} + \sqrt{37} > 4\)
We can check these inequalities:
- Approximate values: \(4 + 1.41 \approx 5.41\) (which is greater than \(6.08\) as \(\sqrt{37} \approx 6.08\)), so this inequality fails.
Thus, this triangle cannot have \(\sqrt{37}\) as one of its sides.
2. **Option 2:** Sides are \(\sqrt{43}\), \(6\), and \(\sqrt{37}\)
- \(\sqrt{43} + 6 > \sqrt{37}\)
- \(\sqrt{43} + \sqrt{37} > 6\)
- \(6 + \sqrt{37} > \sqrt{43}\)
Approximate values:
- \(\sqrt{43} \approx 6.56\) and \(\sqrt{37} \approx 6.08\)
- \(\sqrt{43} + 6 \approx 12.56\), which is greater than \(6.08\)
- \(\sqrt{43} + \sqrt{37} \approx 12.64\), which is greater than \(6\)
- \(6 + \sqrt{37} \approx 12.08\), which is greater than \(\sqrt{43}\)
All inequalities hold, therefore this triangle is valid.
3. **Option 3:** Sides are \(\sqrt{74}\), \(5\), and \(\sqrt{37}\)
- \(\sqrt{74} + 5 > \sqrt{37}\)
- \(\sqrt{74} + \sqrt{37} > 5\)
- \(5 + \sqrt{37} > \sqrt{74}\)
Approximate values:
- \(\sqrt{74} \approx 8.60\)
- \(\sqrt{74} + 5 \approx 13.60\), which is greater than \(6.08\)
- \(\sqrt{74} + \sqrt{37} \approx 14.68\), which is greater than \(5\)
- \(5 + \sqrt{37} \approx 11.08\), which is less than \(\sqrt{74}\)
The last inequality fails, so this triangle cannot have \(\sqrt{37}\) as one of its sides.
4. **Option 4:** Sides are \(5\), \(\sqrt{18}\), and \(\sqrt{37}\)
- \(5 + \sqrt{18} > \sqrt{37}\)
- \(5 + \sqrt{37} > \sqrt{18}\)
- \(\sqrt{18} + \sqrt{37} > 5\)
Approximate values:
- \(\sqrt{18} \approx 4.24\)
- \(5 + 4.24 \approx 9.24\), which is greater than \(6.08\)
- \(5 + 6.08 \approx 11.08\), which is greater than \(4.24\)
- \(4.24 + 6.08 \approx 10.32\), which is greater than \(5\)
All inequalities hold, thus this triangle is valid.
Therefore, the triangles that can have an unknown side length of \(\sqrt{37}\) are **Option 2** and **Option 4**.
1. \(a + b > c\)
2. \(a + c > b\)
3. \(b + c > a\)
We'll evaluate each option to check if \(\sqrt{37}\) can be an unknown side while satisfying the triangle inequality.
1. **Option 1:** Sides are \(4\), \(\sqrt{2}\), and \(\sqrt{37}\)
- \(4 + \sqrt{2} > \sqrt{37}\)
- \(4 + \sqrt{37} > \sqrt{2}\)
- \(\sqrt{2} + \sqrt{37} > 4\)
We can check these inequalities:
- Approximate values: \(4 + 1.41 \approx 5.41\) (which is greater than \(6.08\) as \(\sqrt{37} \approx 6.08\)), so this inequality fails.
Thus, this triangle cannot have \(\sqrt{37}\) as one of its sides.
2. **Option 2:** Sides are \(\sqrt{43}\), \(6\), and \(\sqrt{37}\)
- \(\sqrt{43} + 6 > \sqrt{37}\)
- \(\sqrt{43} + \sqrt{37} > 6\)
- \(6 + \sqrt{37} > \sqrt{43}\)
Approximate values:
- \(\sqrt{43} \approx 6.56\) and \(\sqrt{37} \approx 6.08\)
- \(\sqrt{43} + 6 \approx 12.56\), which is greater than \(6.08\)
- \(\sqrt{43} + \sqrt{37} \approx 12.64\), which is greater than \(6\)
- \(6 + \sqrt{37} \approx 12.08\), which is greater than \(\sqrt{43}\)
All inequalities hold, therefore this triangle is valid.
3. **Option 3:** Sides are \(\sqrt{74}\), \(5\), and \(\sqrt{37}\)
- \(\sqrt{74} + 5 > \sqrt{37}\)
- \(\sqrt{74} + \sqrt{37} > 5\)
- \(5 + \sqrt{37} > \sqrt{74}\)
Approximate values:
- \(\sqrt{74} \approx 8.60\)
- \(\sqrt{74} + 5 \approx 13.60\), which is greater than \(6.08\)
- \(\sqrt{74} + \sqrt{37} \approx 14.68\), which is greater than \(5\)
- \(5 + \sqrt{37} \approx 11.08\), which is less than \(\sqrt{74}\)
The last inequality fails, so this triangle cannot have \(\sqrt{37}\) as one of its sides.
4. **Option 4:** Sides are \(5\), \(\sqrt{18}\), and \(\sqrt{37}\)
- \(5 + \sqrt{18} > \sqrt{37}\)
- \(5 + \sqrt{37} > \sqrt{18}\)
- \(\sqrt{18} + \sqrt{37} > 5\)
Approximate values:
- \(\sqrt{18} \approx 4.24\)
- \(5 + 4.24 \approx 9.24\), which is greater than \(6.08\)
- \(5 + 6.08 \approx 11.08\), which is greater than \(4.24\)
- \(4.24 + 6.08 \approx 10.32\), which is greater than \(5\)
All inequalities hold, thus this triangle is valid.
Therefore, the triangles that can have an unknown side length of \(\sqrt{37}\) are **Option 2** and **Option 4**.
