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.

a

step-by-step explanation:

the answer is:

the correct option:

b.

to solve the problem, we need to remember how to operate to simplify exponential expressions using the logarithms.

we are given the equation:

then, using placing logarith with base 7 on both sides of the equation, we have:

so, rounding the obtained result to two decimal places (nearest hundreth), we have:

hence, we have that the correct option:

b.

have a nice day!
