points a and b are located on the same line segment with point c between them. ac=12 and ab= 15. what is the length of bc
draw the diagram. It is clear that
ac + cb = ab
Now just plug in your numbers
To find the length of segment BC, we can use the segment addition postulate. According to this postulate, if two points A, B, and C are collinear (meaning they lie on the same line), then AB + BC = AC.
Given that AB = 15 and AC = 12, we can substitute these values into the equation:
15 + BC = 12
Now, we need to isolate BC. Let's bring 15 to the other side of the equation:
BC = 12 - 15
Simplifying the equation further, we get:
BC = -3
Therefore, the length of segment BC is -3. However, since lengths cannot be negative, there might be an error in the problem statement or the given information. Please check the values provided for AB and AC to ensure accuracy.
