Question

if lm = 11, then km =

Explanation:

Step1: Identify segment - addition postulate

From the figure, $KM=KL + LM$. Since the two segments $KL$ and $LM$ are congruent (equal - length segments as indicated by the tick - marks), and $LM = 11$, then $KL=LM = 11$.

Step2: Calculate $KM$

$KM=KL + LM$. Substitute $KL = 11$ and $LM = 11$ into the formula. So, $KM=11 + 11$.
$KM = 22$

Answer:

22
