Lori is president of a book club. She has a message she wants to get out to her book club members. On Monday, she called one member and asked that member to call two other members by noon the next day and
repeat the message. How many calls were made by Friday afternoon?

15.36 per mile

but forgot to round

i am pretty sure

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.

hope this by jack monhen

i think its 7.6

if so your welcome
