Question

1. if (lm = 22) and (mn = 15), find (ln).

Explanation:

Step1: Apply segment - addition postulate

If point M lies on line segment LN, then $LN=LM + MN$.

Step2: Substitute given values

Given $LM = 22$ and $MN = 15$, we substitute into the formula: $LN=22 + 15$.

Step3: Calculate the result

$LN=37$.

Answer:

$37$
