Question

if bc is parallel to de then what is the value of de​

Answer 1

Given : bc is parallel to de

To Find : Value Of DE

Solution:

BC || DE

=> ∠ADE  = ∠ABC  ( corresponding angles )

   ∠AED  = ∠ACB   ( corresponding angles )

  ∠A   = ∠ A  common angle

Δ ADE ≈ Δ ABC

=> AD/AB  = DE/ BC

=> AD/(AD + DB) = DE/BC

=> 3/(3 + 2) = DE/10

=> DE = 6

Value of DE = 6
