I am usually really good at these. I just can't figure this one out. Thoughts?

Also, I know that both (1) and (2) are saying the same thing. So the answer is either both can solve separately or neither can solve. However, I just can't get from knowing the 1 angle to figuring out the rest of the problem.

This problem is actually pretty simple.
The question is asking us angle PRS - angle PQR(PQS)

Statement 1: angle QPR = 30
we can deduce that angles RPS + PRS = 90 and QPS + PQS = 90
=> RPS + PRS = QPS + PQS
=> PRS - PQS = QPS - RPS = QPR
=> PRS - PQS = 30
SUFF

Similiarly Solving for statement 2 will show you that its SUFF too

Thus D

Oh wow I can't believe that I didn't see that - I guess all the studying is draining me, lol. Thanks for the explanation!
