Which of the following sets of numbers could not represent the three sides of a triangle? O {6, 10, 15) O {8,18,24) O {11, 19, 29) O {12, 19, 33)

-1   1/6.   you dont subtract the denominators

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.
