Answer:
DE is 12cm. Please mark me as brainliest.
Step-by-step explanation:
∠BAC = ∠CDE (Alternate interior angles)
∠ABC = ∠CED (Alternate interior angles)
∠ACB = ∠ECD (Vertically opposite angles)
So, ΔABC ~ ΔDEC (AAA similarity criterion)
So, AC/CD = AB/DE (Corresponding parts of similar triangles)
6cm/8cm = 9cm/DE
3/4 = 9cm/DE
3(DE) = 36cm
DE = 12cm
