Question

Q-4) In ∆ABC , DE || BC , AD = 4 cm , DB = 6 cm and AE = 5 cm . The length of EC is .​

Answer 1

Answer:

7.5 cm

Step-by-step explanation:

AD/BD =AE/EC (Since a parallel line divides the sides in the same ratio)

4/6 = 5/EC

2/3 = 5/EC

On cross multiplying, we get:

2EC=5 x 3

EC=15/2

EC=7.5 cm
