Lacey y Haley están simplificando expresiones. Haley simplificó x. x’y obtuvo x". ¡Lacey simplificó
r2 + x2 y obtuvo el mismo resultado! Pero sus maestros
les dijeron que solo una simplificación es correcta. ¿Quién
simplificó correctamente y cómo lo sabes?

this may not be at all, but i use the same website you're using for school, and if i'm stuck doing one of these i try to look for it on the section.

step-by-step explanation:

you would need to also lose 1 point for each of the other outcomes for it to be fair.

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.
