Since the condition does not indicate how the points A, B and C are located relative to the other’s arcs, then two options must be considered.
1. If point C lies between points A and B.
AC = AB – BC;
AC = 10.8 – 2.4;
AC = 8.4 cm.
2. If point B lies between points A and C.
AC = AB + BC;
AC = 10.8 + 2.4;
AC = 13.2 cm.
Answer: 1. AC = 8.4 cm. 2. AC = 13.2 cm.
