What is the length of AC?

Step-by-step explanation:

These triangles are similar. That means that the corresponding side lengths exist in proportion to one another.  Namely,

Filling in those values gives us

and cross multiply to solve:

9(140 - x) = 81x and

1260 - 9x = 81x and

1260 = 90x so

x = 14

That means that side length AC is 140 - 14 which is 126. Choice B.

Option B is the right option.

Solution,

hope this helps...

Good luck on your assignment..

let's solve your equation step-by-step.

24−3x=−27

step 1: simplify both sides of the equation.

24−3x=−27

24+−3x=−27

−3x+24=−27

step 2: subtract 24 from both sides.

−3x+24−24=−27−24

−3x=−51

step 3: divide both sides by -3.

−3x

−3

=

−51

−3

x=17

answer:

x=17
