Answer:

Since we have TW ║UV, we can use Thales theorem to calculate SW:

SW/WV = ST/TU

=> SW/40 = 24/48

=> SW = (40 . 24)/48 = 20

Answer: SW = 20

Step-by-step explanation: Upon close inspection, ST is half of TW, and TW is parallel to UV. WV is 40, and since one is ST is 1 / 2 of TU, it makes sense that SW is half of WV, which is 40 units long. With that being said, SW is 20.
