sorry, didnt give the calculations. AB is parallel to DC.
AD is parallel to BC.
∠ CDB = 66°.
∠ CAB = 26°.

Because  DC  and AB are parallel lines cut by a transversal, angle CDB  =  angle DBA = 66°

 

And......by the experior angle theorem....    x  = sum ( angle CAB +  angle DBA )

 

So....  x   =  26 + 66  =   92°
