Answer: 24.15

I'm going to assume this topic is on similarity so,

We know there are 2 triangles made by the lines

Triangle ABC is given AC = 9.2 , BC = 3.2

Triangle CDE is given CD = 8.4

Identify which side corresponds to which

AC corresponds to CE , and BC corresponds to CD

So we can write

CD/BC = CE/AC

which is

8.4/3.2 = CE/9.2

To find CE, bring 9.2 to the other side of the equation

(8.4/3.2)(9.2) = CE

CE = 24.15

Answer:

CE = 24.15 units

Step-by-step explanation:

Here:

[tex] \triangle ABC \sim \triangle EDC [/tex] by AAA axiom.

Since the corresponding sides of similar triangles are proportional, so we can set up the proportions based on corresponding sides.

From the given information:

[tex]\sf \dfrac{AC}{CE} = \dfrac{BC}{DC} = \dfrac{AB }{DE} [/tex]

Taking two of them.

[tex]\sf \dfrac{AC}{CE} = \dfrac{BC}{DC} [/tex]

Substituting the known values:

[tex]\sf \dfrac{9.2}{CE} = \dfrac{3.2}{8.4} [/tex]

We can solve for [tex]\sf CE [/tex] by cross-multiplication:

[tex]\sf 3.2 \times CE = 9.2 \times 8.4 [/tex]

[tex]\sf 3.2CE = 77.28 [/tex]

Divide both sides by [tex]\sf 3.2 [/tex]:

[tex]\sf CE = \dfrac{77.28}{3.2} [/tex]

[tex]\sf CE \approx 24.15 \textsf{(in nearest hundredth)}[/tex]

So, the length of [tex]\sf CE [/tex] is approximately [tex]\sf 24.15 [/tex] units.
