Answer:

[tex] x = 10.4 [/tex]

Step-by-step explanation:

Since ∆ABD is similar to ∆CBE, therefore, the ratio of their corresponding side lengths would be equal to each other. Thus:

[tex] \frac{BD}{BE} = \frac{AD}{CE} [/tex]

BD = 12 cm

BE = x

AD = 27 cm

CE = 23.4 cm

Plug in the values

[tex] \frac{12}{x} = \frac{27}{23.4} [/tex]

Cross multiply

[tex] x \times 27 = 23.4 \times 12 [/tex]

[tex] 27x = 280.8 [/tex]

Divide both sides by 27

[tex] x = 10.4 [/tex]
