Answer:
Step-by-step explanation:
∠ACB and ∠ECD are vertical angles, so ∠ACB = ∠ECD.
∠D = ∠B 
∠A = ∠E
△ABC and △EDC are similar because they have the same angles.

Answer:
   6748'
Step-by-step explanation:
The long diagonal is the third leg of a triangle with the given side lengths and an angle between them that is the supplement of the given angle. Its length can be found from the Law of Cosines.
   a^2 = b^2 +c^2 -2bc·cos(A)
   a^2 = 3473^2 +4822^2 -2·3473·4822·cos(180° -72.23°)
   a^2 = 45,535,553.83
   a ≈ 6748.004
The longer diagonal is about 6758 feet long.
