What is the measure of angle 4 if angle 1 = 76 degrees, angle 2 = 27 degrees and angle 3 = 17 degrees

Step-by-step explanation:

∠1 + ∠2 + ∠3 + a = 360   {Sum of all angles of quadrilateral}

76 + 27 + 17 + a = 360

          120 + a = 360

                    a = 360 -120

a = 240°

a + ∠4 = 360    

240 + ∠4 = 360

∠4 = 360 - 240

∠4 = 120°

an advantage of the standard deviation is that it increases as the dispersion of the data increases. e. the interquartile range is preferred when the data are not skewed or no have outliers. an advantage of the standard deviation is that it uses all the observations in its computation.

the aswere is the one with all 8's and the second one is with the 10,8 and 6
