Question

question point m is on line segment $overline{ln}$. given $ln = 20$ and $lm = 7$, determine the length $overline{mn}$. answer attempt 1 out of 2 $mn=$

Explanation:

Step1: Recall segment - addition postulate

Since point M is on line segment $\overline{LN}$, we know that $LN=LM + MN$.

Step2: Solve for MN

We can rewrite the equation as $MN=LN - LM$. Given $LN = 20$ and $LM = 7$, then $MN=20 - 7$.

Step3: Calculate the value

$MN = 13$.

Answer:

$13$
