The sum of internal angles in parallelogram is 360°
There are 2 angles measured x° and there are 2 angles measured 66°. So the equation will be
∠1 + ∠2 + ∠3 + ∠4 = 360°
x° + x° + 66° + 66° = 360°

Work on it
x° + x° + 66° + 66° = 360°
2x + 132 = 360
2x = 360 - 132
2x = 228
x = 228/2
x = 114

The value of x is 114
