Plz, ! the box plot below shows the total amount of time, in minutes, the students of a class surf the internet every day: a box plot is shown. part a: list two pieces of information that are provided by the graph and one piece of information that is not provided by the graph. (4 points) part b: calculate the interquartile range of the data, and explain in a sentence or two what it represents. (4 points) part c: explain what affect, if any, there will be if an outlier is present. (2 points)

Given: m∠ adb = m∠cdb ad ≅ dc prove: m∠ bac = m∠bca lol

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.
