hi there if you are there
please reply it is a very urgent assignment that I have to send it by today .

im guessing (23,14). hope this : )

i need more details

step-by-step explanation:

c) blue

lol  

why do you ask > .>

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
