Final answer:
To determine the length of line segment KM, you add the lengths of KL and LM, which gives you KM = 15 + 3, resulting in KM = 18 units.
Step-by-step explanation:
The student asked: If point L is on line segment KM, and given KL=15 and LM=3, what is the length of KM?
Solution: To find the length of line segment KM, we simply add the lengths of KL and LM together since L is a point on the line segment KM. Therefore, the length of KM is the sum of KL and LM.
Calculation:
- KM = KL + LM
- KM = 15 + 3
- KM = 18
The length of the line segment bar KM is 18 units.
