Answer:

[tex] x = 11 [/tex]

Step-by-step explanation:

Given that ∆CDE ~ ∆FGH

CD = 25

DE = 35

FG = 65

GH = 8x + 3

Therefore,

[tex] \frac{CD}{FG} = \frac{DE}{GH} [/tex]

(Similarity Theorem)

[tex] \frac{25}{65} = \frac{35}{8x + 3} [/tex]

Cross multiply

[tex] 25(8x + 3) = 35*65 [/tex]

[tex] 200x + 75 = 2275 [/tex]

[tex] 200x + 75 - 75 = 2275 - 75 [/tex]

[tex] 200x = 2200 [/tex]

[tex] \frac{200x}{200} = \frac{2200}{200} [/tex]

[tex] x = 11 [/tex]
