Final answer:
The length of segment VS is 10 units.
Step-by-step explanation:
The length of segment VS can be determined by adding the lengths of the two segments that make up VS. From the information provided, we know that segment VS is comprised of two segments, and the lengths of these segments add up to the length of the resultant segment VS.
Therefore, the length of segment VS is equal to the sum of the two given lengths, which is 10 units (3 units + 7 units).
