Please do not type in capitals it is hard to read and is considered to be shouting.
If the points are co-linear then there are three possible arrangements
1. ABC
2. ACB
3. BAC
if AB=7 cm and BC = 17 cm then arrangement 2 is not possible because 7cm is not greater than 13 cm
In arrangement 1
A 7 cm B 13 cm C
so AC= 20 cm
In arrangement 3
B 7 cm A 7 ??x?? C and BC = 13 cm
so AC = 6 cm
