Given : ABC and AED are straight lines. BE and CD are parallel
AC = 12.3cm
AB = 8.2cm
BE = 3.8cm
AD = 9.15cm
To Find : Length of CD
ED
Solution:
ABC and AED are straight lines.
BE || CD
ΔABE & ΔACD
∠A = ∠ A common
∠B = ∠C ( corresponding angles )
∠E = ∠D ( corresponding angles )
ΔABE ≈ ΔACD (AAA)
=> AB/AC = AE/AD = BE/CD
=> 8.2/12.3 = 3.8/CD
=> 2/3 = 3.8/CD
=> CD = 5.7
AB/AC = AE/AD
=> 2/3 = AE/9.15
=> AE = 6.1
ED = AD - AE = 9.15 - 6.1 = 3.05
