Verified Answer :

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:

\(\frac{LM}{LN}=\frac{x}{ON}\)

\(\frac{18}{10}=\frac{x}{4}\)

Cross multiplying,

\(x=4*1.8 = 7.2\)

Hence the answer is 7.2      :   Answer (A)

Hope it will help :)
