Point A lies on line BC. find the length of the segment AC, if AB = 19 m, BC = 11 m.

Obviously, the segment AB is longer than the segment BC. Therefore, point A cannot lie inside the segment BC. The length of the segment AC will be equal to the difference between the segments AB and BC. Ie – AB-BC = AC.
AB = 19
BC = 11
AC = 19-11 = 8 (m)
Answer: 8 meters
