Answer:
B.14.6
Step-by-step explanation:
To answer this question, it is best to sketch out the scenario, to get a better understanding of the question. Please look at the image for reference.
Make point M anywhere between the N and O on the line NO.
Looking at the sketch, an equation can be made:
NM + MO = NO
Substituting the values for MO and NO:
NM + 12.3 = 26.9
NM = 26.9 - 12.3
NM = 14.6
