Answer:
Step-by-step explanation:
Alright, lets get started.
Please refer the diagram I have attached.
The diagram refers the angle bisector theorem.
Hence using this theorem in our given diagram:
[tex]\frac{LM}{LN}=\frac{x}{ON}[/tex]
[tex]\frac{18}{10}=\frac{x}{4}[/tex]
Cross multiplying,
[tex]x=4*1.8 = 7.2[/tex]
Hence the answer is 7.2 : Answer (A)
Hope it will help :)
