The length of the segment AB is 50cm. point M and N lie on this segment. Find the length of the segment MN, if AM = 23 cm, NB = 21 cm.
Let us write out which segments the segment AB consists of:
AB = AM + MN + NB, we express from this expression, which is equal to the segment MN:
MN = AB – AM – NB.
We know that AB = 50 cm, AM = 23 cm, NB = 21 cm.
We substitute the data into our expression and find the length of the segment MN:
MN = 50 cm – 23 cm – 21 cm = 6 cm.
The length of the segment MN is 6 cm.
