Getting answer out of a ConditionalExpression[]

I'm interested in getting a plot-able array out of the following:
Clear[x]
Table[Solve[(1 + Exp[I*(n*Pi/6 + x)])*(1 + Exp[-I*(n*Pi/6 + x)]) == 
   1/((1 - Exp[I*n*Pi/6])*(1 - Exp[-I*n*Pi/6])), x], {n, 1, 11}]

There are two problems:
1) getting the answers out of the 
{x -> ConditionalExpression[
   1/6 (-\[Pi] + 6 I (-((I \[Pi])/6) + 2 I \[Pi] C[1])), 
   C[1] \[Element] Integers]}
and 
2) removing the C[1] terms

I'm particularly interested in plotting the phase angles with log expressions:
{x -> ConditionalExpression[
   1/2 (-\[Pi] + 2 I (2 I \[Pi] C[1] + Log[1/4 (-3 - I Sqrt[7])])), 
   C[1] \[Element] Integers]}, {x -> 
  ConditionalExpression[
   1/2 (-\[Pi] + 2 I (2 I \[Pi] C[1] + Log[1/4 (-3 + I Sqrt[7])])), 
   C[1] \[Element] Integers]}
