Hi shannonalex,
This is one of the trickier, multi-shape geometry questions floating around the GMAC CATs - and most Test Takers get it wrong. Here's a link to a discussion on this question:

GMAT assassins aren't born, they're made,

In DS, Variable approach is the easiest and quickest way to find the answer without actually solving the problem.
Remember equal number of variables and equations ensures a solution.
In original condition, angle X+angle SQP + angle SUP + angle P(90)=360. So we have 3 variables (X, SQP, SUP) and 1 equation. 2 more equations are needed.
So, the answer is C.
Why C? If you know our own innovative logics to find the answer, you don't need to solve the problem.

From the original condition, angle x + angle SQP + angle SUP + angle P (90) = 360
We have 3 variables and we already have 1 equation above, so we need 2 additional equations, so the answer is C.
