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.
