Answer:

5.6 cm

Step-by-step explanation:

D is the mid point of AB (given )

therefore, AD=BD ------- equation 1

DE || BC (given)

AD/ BD = AE/ EC ( basic proportionality theorem )

from equation 1 we get,

AD/AD = AE/ EC

1 /1= 2.8 / EC

1= 2.8 / EC

EC= 2.8 cm

AC= AE+EC

AC= 2.8+2.8

AC = 5.6 cm

Hope this hepls
