Question

Help I really just suck at math

Answer 1

We need more details to answer.  You did forget to mark ST as 16 but I see no problem with the NQ.  NQ should be self-similar to SU.

Thats about 9:12.  She should have enough information for them to be self-similar because you can find angle S by adding angle T and U together and subtracting 180 by the sum of those numbers.

I am not sure what the question is asking though specifically so can you provide more info
