Answer:

26 2/3 in

Explanation:

Corresponding sides are proportional, so we can write ...

EC/DC = EA/DB

(ED +20)/20 = 14/6

ED/20 +1 = 7/3 . . . . . . eliminate parentheses, simplify fraction

ED/20 = 4/3 . . . . . . . subtract 1

ED = 20(4/3) = 80/3 = 26 2/3 . . . . multiply by 20

ED is 26 2/3 inches.
