Answer:
x = 11 , CE = 98
Explanation:
• If 2 chords are congruent, then they are equidistant from its centre , so
CE = FC , that is
10x - 12 = 8x + 10 ( subtract 8x from both sides )
2x - 12 = 10 ( add 12 to both sides )
2x = 22 ( divide both sides by 2 )
x = 11
Then
CE = 10x - 12 = 10(11) - 12 = 110 - 12 = 98
