Answer 1

Answer:

Ab and De are also parallel

Answer 2

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
