Question

cooldown 5.4 missing length pw 10ptswhat must be true about segment mn?it is units long.

Explanation:

Step1: Check if MN is a mid - segment

Since \(\frac{AN}{NC}=\frac{1}{2}\) and \(\frac{AM}{MB}=\frac{1.8}{3.6}=\frac{1}{2}\), by the converse of the triangle mid - segment theorem, \(MN\parallel CB\) and \(MN=\frac{1}{2}CB\).

Step2: Calculate the length of MN

Given \(CB = 4\) units. Using the mid - segment formula \(MN=\frac{1}{2}CB\), we substitute \(CB = 4\) into the formula. So \(MN=\frac{1}{2}\times4\).

Answer:

\(2\)
