On ray AD, draw segments AB and BC so that AB = 3cm and BC = 4cm 5mm What is the length of segment AC?

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.
