Prove that cos A/1- sin A + cos A/1+sin A = 2tan A

i believe the answer is d.

hope it you! : d

the ratio of balloons to tables is 5: 2 and the constant variation is 5.

the equation is y=5x

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.
