ANSWER THE QUSTION FOR 25 POINTS

D) 4th one is the correct answer.

Step-by-step explanation:

original, question line : 4/5 then it can be converted to percentage 4/5 * 100 = 80%

a) 2/3 * 100 = 200/3

b) 5/8 * 100 = 62.5%

c) 10/12 * 100 = 250/3 %

d) 8/10 * 100 = 80% ..this matches with the required first line and applicable.

∵ 4th one is correct according to steps. : D

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
