Answer:
[tex]x=229[/tex]°
Step-by-step explanation:
The given figure is a quadrilateral or a figure with (4) sides. The sum of angles in a quadrilateral is (360) degrees. One can apply this here by stating the following:
[tex]25 + x + 23 + 83 = 360[/tex]
Simplify,
[tex]25 + x + 23 + 83 = 360[/tex]
[tex]131+x=360[/tex]
Inverse operations,
[tex]131+x=360[/tex]
[tex]x=229[/tex]
