Answer:
ED = 6.5 cm
BE = 14.4 cm
Step-by-step explanation:
AB/BC = AE/ED => ED = BC×AE/AB
ED = 5×26/20 = 130/20 = 6.5 cm
AB/AC = BE/CD => BE = AB×CD/AC
BE = 20×18/25 = 360/25 = 14.4 cm
The length of ED is 6.5cm.
The length of BE is 14.4 cm.
In ΔACD
BE ∥ CD
In ΔACD and ΔABE
BE ∥ CD
∠ACD =∠ABE (corresponding angles)
∠ADC = ∠AEB (corresponding angles)
∠A = ∠A (common angle)
∴ΔACD ∼ ΔABE
So, The corresponding sides are in proportion.
Now, find ED
[tex]\frac{AB}{BC}=\frac{AE}{ED}\\ED=AE(\frac{BC}{AB}) \\ED=26(\frac{5}{20} \\ED=6.5 cm[/tex]
Now, find BE
[tex]\frac{AB}{AC} =\frac{BE}{CD} \\BE=CD(\frac{AB}{AC})\\BE=18(\frac{20}{25})\\BE=14.4 cm[/tex]
Therefore, the length of ED is 6.5cm and the length of BE is 14.4 cm.
