Answer 2

Answer:

Please mark me as Brainliest!!

Step-by-step explanation:

Either the figure is wrong or the question is wrong, it must be in place of B in DE||BC it should be AC, so it is DE||AC

Now, by similarity we can easily show that

BD/AD=BE/EC

or

by midpoint theorem of class 10,

we can easily show the relation

so the answer should be EC=6cm
