Answer:
x = 130
Step-by-step explanation:
The sum of the exterior angles of a polygon is always 360
140 + x + 56+ 34 = 360
Combine like terms
230 +x = 360
Subtract 230 from each side
230+x-230 = 360-230
x =130
I don't think you provided all the options.
Because of this, I'm providing a guess until you have the time to provide the other equations...
I'd say the correct answer is:

Again, this is JUST an assumption.
I attached a screenshot in case you wished for relatively adequate proof.
If you can, please provide the other answer options, so I can give a more accurate answer. :)
Hey!~
To get the answer all you would need to do is divide 589/31=19.
If you round $19 dollars up, the closest number would be $20. The answer is B. $20.00.
Hope this helps and have a great day!
