1) S is your observation point on Earth. AB is actually the diameter of Jupiter. So when you rotate your instrument from A to B (which are end points of the diameter of Jupiter), you rotate by angle theta (which is the parallax angle). The rest is simple application of the formula discussed. 2) The most important thing to remember is that 360 degrees = 2*pi radians = 2*3.14 radians = 6.28 radians. Just do 2-3 more examples from NCERT book and I think your confusion will be cleared. I hope I have answered your queries sufficiently.
