Answer:

$|LN| = 24$

Step-by-step explanation:

Given

$LM:MN:NO = 3:1:2$

$LO = 30$

Required

Find LN

$LN = LM + MN$

From the ratio, LM = 3 and MN = 1

So:

$LN = 3 + 1$

$LN = 4$

LN and NO can be represented as:

$LN : NO = 4 : 1$

The length of LN is then calculated as:

$|LN| = \frac{LN}{LN+NO}*|LO|$

$|LN| = \frac{4}{4+1}*30$

$|LN| = \frac{4}{5}*30$

$|LN| = \frac{4*30}{5}$

$|LN| = \frac{120}{5}$

$|LN| = 24$
