Answer: The length of NM is 14.6 units.
Step-by-step explanation: As shown in the attached figure below, the point M lies between the points N and O on NO. MO = 12.3 and NO = 26.9.
We are to find the length of NM.
Since the point M lies on the straight line NO, so from the figure, we get
\(NM+MO=NO\\\\\Rightarrow NM=NO-MO\\\\\Rightarrow NM=26.9-12.3\\\\\Rightarrow NM=14.6.\)
Thus, the length of NM is 14.6 units.
