Find the sum of the series. 5.)A1=2 An=128 r=3
6.) A1=-5 n=10 r=2
7.) A1=1/2 n=14
r=4
8.) A1= 7 An=1414 r=3

95.03 is the answer. hope this !

provide more details to solve it

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.
