Given triangle ABC, which equation could be used to find the measure of ∠B? cos m∠B = 2 square root of 5 all over 5
sin m∠B = square root 5
cos m∠B = square root of 5 over 2
sin m∠B = 2 square root of 5 all over 5

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

y -5 = (-1/4)(x + 8)
