The longest side, EC, is opposite the largest angle, D. Hence you can eliminate all but the first and last answer choices.
The shortest side, CD, is opposite the smallest angle, E. Hence the first choice is the correct one.
... m∠D > m∠C > m∠E
You will need to divide. You can divide using a google calculator

Here's a counterexample: let
We choose the subsets as follows:
It is true that and and that , but
