Step-by-step explanation:

divided 12 by three since it mirrors the shape on a smaller scale. you get 4. multiply that by five and there's your answer

u use similar figures to find it out

3/12=x/5

then u cross multiply

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
