POINTS A, B, AND C ARE COLLINEAR. IF AB=7AM AND BC =13CM WHAT IS AC ANSWER
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
To find the length of AC, we need to add the lengths of AB and BC since they both lie on the same line.
1. Let's start by adding the lengths AB and BC together:
AB = 7 units
BC = 13 units
2. Adding AB and BC, we get:
AB + BC = 7 + 13 = 20 units
Therefore, the length of AC is 20 units.
