Answer:

  x = 4

Step-by-step explanation:

The product of the lengths of the segments of each chord is the same.

  AE·EB = CE·ED

  (x+2)(8) = (3x)(4) . . . . . substitute the given lengths

  8x +16 = 12x . . . . . . . . simplify

  16 = 4x . . . . . . . . . . . . . subtract 8x

  4 = x . . . . . . . . . . . . . . . divide by 4
