The length of the segment AB is exactly 50cm. Points M and N lie on this segment. Find the length of the segment MN if: a) AM = 15cm, NB = 19 cm; c) AM = 23cm, NB = 21cm b) AN = 38cm, MB = 26 cm; d) AN = 42cm, MB = 34 cm
AB = 50cm; MN = AB – AM – NB = AN – MB.
a) AM = 15 cm, NB = 19 cm – MN = AB – AM – NB = 50 – 15 – 19 = 16 cm.
b) AM = 23 cm, NB = 21 cm – MN = AB – AM – NB = 50 – 23 – 21 = 6 cm.
c) AN = 38 cm, MB = 26 cm – MN = AN – MB = 38 – 26 = 12 cm.
d) AN = 42 cm, MB = 34 cm – MN = AN – MB = 42 – 34 = 8 cm.
