Allie answered 72% of the questions on her math test correctly. if she answered 18 questions correctly, how many questions were on the test?

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.

Iwill give you ! what is the measure of ∠v ?
