Step-by-step explanation: He goes up 3 floors and he is currently on the fith one so he is now on the 8th floor

8+2 because he still has to go down to floors to get to the underground floor

He has to go down 10 floors

d. is the correct answer

step-by-step explanation:

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
