Final answer:
To find the length of line segment TV, simply add the lengths of segments TU and UV, which are 12 and 3 units respectively, resulting in TV having a length of 15 units.
Step-by-step explanation:
To determine the length of the line segment TV, we need to understand that the length of a line segment is the sum of the lengths of its parts. Here, we know that point U is on line segment TV, and we are given that UV = 3 units and TU = 12 units. We can sum these two distances to find the length of TV.
Step-by-step explanation:
- Identify the given lengths: TU and UV.
- Sum the lengths: TU + UV = TV.
- Substitute the known values: 12 units (for TU) + 3 units (for UV).
- Calculate the sum: 12 + 3 = 15 units.
Therefore, the length of the line segment TV is 15 units.
