8. Alex had 4 plays during his football game. One he ran for 80 yards and made a touchdown. Another he lost 14 yards, then he made a first down by
running 6 yards and then lost 10 yards when he was being chased and fell
backwards. How many yards did Alex actually gain during this game? *

step-by-step explanation:

what was your answer?

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.
