8 meters

Step-by-step explanation:

First, let's find the scale factor by dividing the value of the corresponding sides.

20/15 = 1.33...

This means that the scale factor is 1.3

To find the length of the missing side, multiply the length by the scale factor.

6(1.3) = 8

Therefore, the value of side c is 8 meters.

step-by-step explanation:

you divide the denominator by the numerator on both sides and if the quotients are equal then the fractions are equivalent

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
