Kayla bought 9/4 pounds of apples what is the weight as a mixed number

In the figure below, ∠dec ≅ ∠dce, ∠b ≅ ∠f, and segment df is congruent to segment bd. point c is the point of intersection between segment ag and segment bd, while point e is the point of intersection between segment ag and segment df. the figure shows a polygon comprised of three triangles, abc, dec, and gfe. prove δabc ≅ δgfe.

Me. i can't figure out this question. give an explanation too. .

Use circumcenter theorem to solve for the given values
