Answer:
LN = 15
Step-by-step explanation:
The arrows on the line segments indicate they are parallel.
[tex]\implies \overline{KM} \parallel \overline{JN}[/tex]
Triangle Proportionality Theorem
If a line parallel to one side of a triangle intersects the other two sides of the triangle, then it divides these two sides proportionally.
[tex]\textsf{If }\overline{KM} \parallel \overline{JN}, \textsf{ then }\dfrac{LK}{LJ}=\dfrac{LM}{LN}[/tex]
Given:
⇒ LK = JL - JK = 30 - 18 = 12
Substituting the values into the equation and solving for LN:
[tex]\begin{aligned}\implies \dfrac{LK}{LJ} & = \dfrac{LM}{LN}\\\\\dfrac{12}{30} & = \dfrac{6}{LN}\\\\12LN & = 30 \cdot 6\\\\LN & = \dfrac{180}{12}\\\\LN & = 15\end{aligned}[/tex]

Answer: LN = 15
Make a proportional relationship:
[tex]\sf \dfrac{LN}{JL} = \dfrac{LM}{KL}[/tex]
Insert the values:
[tex]\rightarrow \sf \dfrac{LN}{30} = \dfrac{6}{30-18}[/tex]
cross multiply:
[tex]\rightarrow \sf LN = \dfrac{30(6)}{12}[/tex]
Simplify:
