Answer:
26 2/3 in
Step-by-step 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.
