Answer:
The value of bc is 5.9 units.
Step-by-step explanation:
Given information: b is between a and c, ac=15.8 and ab=9.9.
We need to find the measure of bc.
Since b is between a and c, therefore the segment ac is the sum of two segments ab and bc.
Substitute ac=15.8 and ab=9.9 in the above equation.
Subtract 9.9 from both sides.
Therefore the value of bc is 5.9 units.
