After a lesson on exponents, tia went home and said to her mom,"i learned that 10 to the power of 4 is the same as 40,000." she has made a mistake in her thinking. use words, numbers, or a place value chart to tia correct her mistake. show the actual solution

i think it would be 42cm

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
