For the convenience of calculations, we express the length of the BC segment in cm.Since there are ten mm in one cm, then:
BC = 4 cm 5 mm = 4.5 cm.
Now let’s calculate the length of the AC segment. To do this, add the lengths of the segments AB and BC:
AC = 3 + 4.5 = 7.5 (cm).
Answer: The length of the AC segment is 7.5 cm.
