HELP ASAP There are 15 students in Dana’s math class (not including her). On a par-
ticular test, the teacher averages the percentages and finds that if Dana’s
score is included, the average score decreases by 2%. What is the highest
possible score Dana could have gotten?

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.
