Are students who get high grades in Biology more likely to get high grades in American Literature? Students who are good in one subject tend to be good at other subjects, but is the tendency significant? To answer this question, suppose Isaac acquires course grade-point average (GPA) data from a random sample of 40 students who took both Biology and American Literature.

step-by-step explanation:

place r′ so that qr′ is parallel to the tangent.

now we get that ∠r′py=∠pr′q, where y is on the tangent, on the opposite side of p from x.

also, because of the symmetry, ∠r′py=∠qpx.

finally, note that no matter where we place r, as long as it's on the correct arc, we have ∠prq=∠pr′q.

stringing all these equalities together, we end up with ∠prq=∠qpx.

this picture will show how its going to look like.
