really? repost after one minute?
impatient much?
and you didn't even fix your error? *tsk*

From what you have said, PQR is basically an equilateral triangle.
(a) Since you have not said anything about where S is, there's no way to calculate angle PSR.
for (b) after you know angle S, then you have an isosceles triangle PSR, and the base angles are easy to find.
