ANSWER
DE > EC > CD
EXPLANATION
Let us make a sketch of triangle CDE:
Let us first find the measure of angle E.
The sum of angles in a triangle is 180 degrees. This means that:
58 + 86 + 144 + =>
The sine of the angle of a triangle and side opposite that triangle is proportional for every angle and side of a triangle.
That is, the ratio of the sine of an angle and the side opposite that angle is constant for a triangle. This is known as the Sine Law.
This law implies that the bigger an angle of a triangle is, the larger the side opposite it and vice versa.
Therefore, since DE > EC > CD
That is the answer.
