A polygon with 4 sides is shown with its exterior angles. The exterior angles are 140 degrees, 34 degrees, 56 degrees, and x degrees. What is the value of x?

The exterior  angles  will sum to  360°

 

Therefore

 

140 + 34 + 56 + x  =  360    simplify

 

230 +x  = 360    subtract  230 from both sides

 

x  =  130°
