To find the length of side EC, we first need to find the scale factor used for the dilation.
Since the scale factor is 22, we can find the length of side EC by dividing the length of side E'C' by the scale factor:
EC = E'C' / scale factor
EC = 8686 / 22
EC = 394
Therefore, the measure of side EC is 393.
