Answer: x = 96
---------------------------------------
Work Shown:
The sum of the exterior angles for any polygon is 360 degrees. So add up the three exterior angles, set the sum equal to 360 and solve for x
130+134+x = 360
264+x = 360
x+264 = 360
x+264-264 = 360-264
x = 96
As a check,
130+134+x = 130+134+96 = 360
so the answer checks out
