The correct answer is B.LM = 11 and LN = 22.

1. Recall the property of a midpoint:

If a point is the midpoint of a line segment , then by the definition of a midpoint, it divides the line segment into two congruent sub - segments. That is, .

We are given that . Since (because is the midpoint of ), then .

2. Use the segment addition postulate:

The segment addition postulate states that for three collinear points , , and ,
