The length of the segment a q is 8 cm, point B lies between the points A and C. Find the length

The length of the segment a q is 8 cm, point B lies between the points A and C. Find the length of the segment AB if the length of the segment BC is 3 cm.

Since point B lies between points A and C and on one segment, in order to find out the length of segment AB, you need to subtract the length of segment BC from the entire length of segment AC:

AB = AC – BC;

AB = 8 – 3;

AB = 5 (cm).

Answer: the length of the segment AB is 5 centimeters.
