A convex polygon has 33 sides what is the sum of the interior angles

127

whether it's diameter, or radius, i believe if i remember correctly from school, every amount has to always add up to 180. so if you take 53, and starting adding, long story short, taking 127 and adding it to 53, gives you 180.

i'm assuming that it's c.)   volcanoes built the mountains and earthquakes tore them down.
