Answer: 
Step-by-step explanation:
 By definition, the sum of the exterior angles of a polygon is 360 degrees.
 Knowing this, you can write the following equation:
 
 Then, you must solve for "x" in order to find its value. To do it, you can follow these steps:
 1. You need to add the like terms:
 
 2. Now, subtract 40 from both sides of the equation:
 
 3. Finally, you must divide both sides of the equation by 4. Then:
