only needs 75% of the piece she cut off. how
many inches of ribbon does kelly end up using
for her project?

20

Step-by-step explanation: Cause 60-20=40

d) by the cross product property, ab^2 = bc multiplied by ad

step-by-step explanation:

we are given

in the given triangle abc

angle a is 90° and segment ad is perpendicular to segment bc

we can see that

triangle(abc) and triangle(abd) are similar because they have common side and same angle (90 degree)

so, triangles(abc) and abd are similar

since, they are similar

so, the ratio of their sides must be equal

we get

now, we can cross multiply

and we get

so, this could be step to prove it

your question is incomplete, write all the numbers in the sequence that it tells you.
