a nonagon has angles that measure, 150, 125, 130, 160, 140,140,150,110 what is the missing angle
The sum of the interior angles of a nonagon is 1260 degrees. If we add up the given angles, we get 1205 degrees. Subtracting 1205 from 1260, we get 55 degrees. Therefore, the missing angle measures 55 degrees.
