Plz help geometry?

This question is poorly made.

There is no other information that can allow us to precisely determine those four lengths.

By guessing what this low-quality question wants to ask
If you make the assumption that STUV is a square,
then you can get VU = TU = 15.

SU = TV = 15sqrt(2) = 21 (nearest tenth)
SW = 15sqrt(2)/2 = 11 (nearest tenth)

However, such an assumption is not stated in the question and thus those answers I typed cannot be rigorously deduced.

I recommend complaining to your teacher about this low-quality question, as formally speaking the answer is "cannot be determined".
