The school made $2,800 on the school carnival. The second and fifth grade classes each made only $200. The kindergarten and four
th grade classes each made double the second grade's amount. The first and third grades made the same amount of money. How much did each grade level make?
Since the line is 180 degrees, and both of the angles that are measured would equal 180, then all we need to do is take 180 - 131 to get 49 degrees. Hope this helped!
