| **On a segment KM with a length of 34 cm, points A and B were marked so that KA = 21 cm, BM = 18 cm. What is the length of segment AB. Is it necessary to rearrange the letters?**

Let us calculate how many centimeters the total length of the spacecraft and VM segments corresponds, if we know, based on the conditions of this task, that the length of the spacecraft segment is 21 centimeters, and the length of the spacecraft segment is 18 centimeters:

21 + 18 = 39.

Let us calculate how many kilograms the length of the segment AB corresponds to, if we know, based on the conditions of the task, that the length of the segment KM is 34 centimeters:

39 – 34 = 5.

Answer: The length of the BA segment is 5 centimeters. Point B lies between K and A.
