Question

problem 9: (first taught in lesson 45) tell whether the following numbers can represent the side lengths of a triangle: 3, 4, 5. after you pick your answer press go. yes no

Explanation:

Step1: Check triangle inequality

For three side lengths \(a\), \(b\), \(c\) (\(a\leq b\leq c\)), check \(a + b>c\). Here \(a = 3\), \(b = 4\), \(c = 5\).
\(3+4>5\)
\(7>5\) (True)

Step2: Conclusion

Since the triangle inequality holds.

Answer:

Yes
