Find the value of x.

Answer:
[tex]x=64^{\circ}[/tex]
Step-by-step explanation:
We know that sum of angles of a quadrilateral is equal to 360 degrees.
It means,
[tex]\angle X+\angle Y+\angle Z+\angle W=360\\\\100+130+66+x=360\\\\296+x=360\\\\x=360-296\\\\x=64^{\circ}[/tex]
So, the value of x is equal to [tex]64^{\circ}[/tex].
