Calculate the length of the segment ac, check the result by measuring. AB = 5cm 2mm CB = 1cm 8mm AC =?

1) Let’s draw the segments, observing the given dimension.

The figure shows that the segments AB and CB form a segment AC, the length of which will be equal to the sum of their lengths.

AC = AB + BC = 5 cm 2 mm + 1 cm 8 mm = 7 cm.

2) Check if the solution is correct by attaching a ruler to the figure.

The length of the segment AC is indeed 7 cm.
