playing the horses: in horse racing, one can make a trifecta bet by specifying which horse will come in first. which one will come in second, and which will come in third, in the correct order. one can make a box trifecta bet by specifying which three horses will come first, second, and third, without specifying the order. in a nine-horse field, how many different ways can one make a trifecta bet?

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
