Point C belongs to the segment MN. Find the length of the MC segment if MN = 17 cm, CN = 6 cm.

Given:
segment MN,
point C belongs to the segment MN,
MN = 17 centimeters,
CN = 6 centimeters.
Find the length of the MC segment -?
Solution:
Consider the segment MN. Since point C belongs to the segment MN, the length of this segment is equal to the sum of the lengths of the segments MC and CN.
Therefore, the length of the segment MN is found by the formula:
MN = MC + CN;
MС = MN – CN (substitute instead of MN = 17 centimeters and CN = 6 centimeters);
MС = 17 – 6;
MС = 11 centimeters.
Answer: 11 centimeters.
