There are 14 boys and 5 girls in the school jazz band. Find the ratio of the number of boys in the band to the total number of students in the band.

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.

Are the corresponding angles congruent? explain why or why not.

Which will form a composite function?
