Final answer:
To find the length of segment UV when TV = 7 and TU = 2, subtract the length of TU from TV. The calculation is TV - TU = UV, which results in 7 - 2 = 5. Consequently, the length of UV is 5 units.
Step-by-step explanation:
The student is asking how to find the length of segment UV given that point U is on line segment TV, with the lengths TV = 7 and TU = 2. Since U is between T and V, we can find the length UV by subtracting the length of TU from the total length TV.
Step 1: Identify the total length of the segment TV, which is given as 7 units.
Step 2: Determine the length of the segment TU, which is given as 2 units.
Step 3: Subtract the length of segment TU from the total length of segment TV to find the length of segment UV.
The calculation would be: TV - TU = UV, which is 7 - 2 = 5. Therefore, the length of segment UV is 5 units.
