Answer:
Explanation:
To find the exact length of the line segment, we need to measure it using a ruler or other measuring tool. The length can then be recorded in units such as inches or centimeters.
To estimate the length of the line segment to the nearest tenth of a unit, we can use rounding. For example, if the line segment appears to be approximately 3.7 units long, we can round that to 3.8 units. However, it's important to note that this method of estimation may not be entirely accurate and should be used with caution.
