m∠AED = m∠AEB + m∠BEC + m∠CED
179 = 105 + x + 40
x = 179 - (105+40) = 34
x = 34
A)The outlier if the data is 28 because it is 30+ numbers away from the next number. B) The mean for this data is 67.45. C) it would be 71.4 without the outlier. P.S to find the mean you add all the numbers together and then divide it by however many numbers there are. Hope this helps
