In triangle ABC ,DE || BC
AD/ DB ,= AE/ EC
AD/ DB = AE ( AC- AE )
3/ 5 = AE ( 4.8 - AE )
3( 14.8- AE ) = 5 AE
14.4 - 3AE = 5AE
14.4 = 5AE + 3AE
14.4 = 8AE
AE = 14.418 cm
AE = 1.8 cm

Answer:
AE = 1.8 cm
Step-by-step explanation:
In triangle ABC ,DE || BC
AD/ DB ,= AE/ EC
AD/ DB = AE ( AC- AE )
3/ 5 = AE ( 4.8 - AE )
3( 14.8- AE ) = 5 AE
14.4 - 3AE = 5AE
14.4 = 5AE + 3AE
14.4 = 8AE
AE = 14.418 cm
AE = 1.8 cm
