Line P R and Line Q S are diameters of circle T. What is the measure of Arc S R?

I don't have enough information to give a single numeric answer. PR and QS being diameters only tells us that P and R are opposite points and Q and S are opposite points (they meet at the center T). That implies the four central arcs around the circle come in two equal pairs:

- arc SR = arc PQ
- arc RQ = arc PS
- arc SR + arc RQ = 180°

So the measure of arc SR depends on the angle between the diameters. For example, if PR and QS are perpendicular, each of the four arcs is 90° so arc SR = 90°. If you can tell me the measure of one of the arcs or the angle between the diameters (or upload the diagram), I can compute arc SR.
