<span>The expansion of the warehouse will not affect the dimensions of the surrounding fence.</span>
since the triangles are similar
angle DEC = 60 degrees

BAC = DCE = 64
CBA = EDC = 56
DEC = 180 -56 -64 = 60 degrees
used angle-angle theorem
The correct answer, or in this case, the incorrect statement is the mean is not affected by the existence of an outlier.
