U Question 2
10 pts
Molly wants to participate in the "Battle of the Books" reading challenge. She must choose 4 books from the
14 possible choices. How many different ways can she choose 4 books?

step-by-step explanation:

i think its about 8

the correct answer is c) 2.

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.
