Question

could 8.8 cm, 8.0 cm, and 8.8 cm be the side lengths of a triangle?
choose 1 answer:
a yes
b no

Explanation:

Step1: Check triangle inequality theorem

For three side lengths \(a\), \(b\), \(c\) (\(a\leq b\leq c\)), the triangle inequality theorem states that \(a + b>c\). Here \(a = 8.0\), \(b = 8.8\), \(c = 8.8\).

Step2: Calculate \(a + b\)

\(a + b=8.0 + 8.8=16.8\)

Step3: Compare \(a + b\) with \(c\)

Since \(16.8>8.8\)

Answer:

A. Yes
