True or False: (EXPLAIN your answer) If angle CEF is complementary to angle DCF, then angle DCF is congruent to angle FEG.

True

Step-by-step explanation:

Givens:

From if part: m<CEF+m<DCF=90

From picture: m<CEF+m<FEG=90

Subtracting the equations we get:

m<DCF-m<FEG=0

Adding m<FEG on both sides:

m<DCF=m<FEG

So true.

c

step-by-step explanation:

it isn't d, because the interquartile range is from 27-57. and the interquartile range is basically half the data, it's pretty obvious.

it isn't b, because like i said earlier, the interquartile range is from 27-57. 57-27 is 30. the real range has to be longer

not a either. although it looks like it, 3/4 of the data is not greater than 27. but if c is wrong than this should be correct

the correct answer is c, because 13 is the point in which the plot starts

trapezoid

step-by-step explanation:

first i plotted all my points on a grid graph

i made sure all of them were in the correct quadrant

then i saw it was a trapezoid or a quadrilateral
