Answer:

13.3

Step-by-step explanation:

If AM is 6 and MB is 4, the total length of AB is 10. The ratio of the sides ΔABC and ΔAMN is going to be 5:3 since that 10 divided by 6 can be simplified to 5 divided by 3. If AN is 8 and the ratio of AN to AC is 3:5, the value of AC could be rounded to 13.3.
