Auma certa hora da manhã, o sol incidindo sobre o topo de um edifício projeta uma sombra de 32 m. no mesmo instante, a sombra de um poste com 9 m de altura, localizado ao lado do edifício, mede 12 m . neste caso, a medida da altura do edifício é?

sorry, i can't understand your question. will later if you describe more clearly!

: )

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

the answer to your question is minor arc.

if the angular bisector of an triangle bisects the opposite side, prove that the other two sides are equal.
