# The length of the segment AB is 50 cm. Points M and N lie on this segment.

The length of the segment AB is 50 cm. Points M and N lie on this segment. Find the length of the segment MN if: AN = 42 cm, MВ = 34 cm.

Let us determine how many centimeters the total length of the segments AN and MB is equal to, knowing by the problem statement that the length of the segment AN is 42 centimeters, and the length of the segment MB is 34 centimeters:

42 + 34 = 76.

Let us determine how many centimeters the length of the segment MN is, knowing by the condition of the problem that the length of the segment AB is 50 centimeters:

76 – 50 = 26.

Answer: The length of the segment MN is 26 centimeters.
