Question

here de=bc find x( triangle)
AD equals to 3
DB equals to 6
DE equals to 4
BC equals to x​

Answer 1

Answer:

12 cm

Step-by-step explanation:

Δ ADE ~ Δ ABC ===> $\frac{AD}{AB}$ = $\frac{DE}{BC}$

AD = 3 cm, AB = (3 + 6) = 9 cm, DE = 4 cm, BC = x cm

$\frac{3}{9}$ = $\frac{4}{x}$

$\frac{1}{3}$ = $\frac{4}{x}$ ===> x = 12 cm
