Jolene is creating a model of a pyramid. the model created will need to be scaled up from the blueprint.

triangle acb, point d is on segment ac between points a and c, point e is on segment bc between points b and c

if segments de and ab are parallel, which of the following expressions will jolene determine the length of segment ac?

Step-by-step explanation:

We are given that

Jolene is creating a model of a pyramid .

In triangle ACB , point D is on segment AC and lies between A and C.

E is on segment BC and lies between B and C.

If segment DE is parallel to segment AB.

We have to find the expression which will help Jolene to determine the length of segment AC.

By triangle proportionality theorem,

Adding 1 on both sides then, we get

This is required expression which will help to determine the length of segment AC.

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
