I GIVE BRAINLIEST
Can someone help me on both of they pls.

for the first one its 3 y he second one is 8 and the last one is 5 the second one isn7 and the third one is 2

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

i think it will be zero as slope has a formula of difference between initial and final distance divided by itz time interval
