Step-by-step explanation:

Triangle CFB is similar to, but not congruent to triangle EDB. We know angles CBF and EBD are congruent, because they are vertical angles.

We know angles CFB and EDB are congruent, because they both intercept the same arc CE. Hence two of the angles in each triangle have the same measure, and we can claim AA similarity.

There is nothing about the figure that requires corresponding sides to be the same length, so we cannot claim the triangles are congruent.

The angle marked 72° is the average of the measures of arcs DF and CE. Then arc CE = 2×72° -98° = 46°.

__

There is nothing in the figure that would indicate the measures of arcs CF or ED, except that we know their sum must be 216°. (It is the difference between 360° and the sum of 98° arc DF and 46° arc CE.)

The "central angle" in the last offered statement is not specified. Certainly, the marked 72° angle is not a central angle, as its vertex is not at point A.
