Answer:
Pentagon =5 sides
exterior angle =360/5=72°
Interior angle =180 -72=108°
polygon of 12 sides
exterior angle =360/12=30°
Interior angle =180-30=150°
hexagon =6 sides
exterior angle =360/6=60°
Interior angle =180-60=120°
octagon=8 sides
exterior angle =360/8=45°
Interior angle =180-45=135°
hope it helps...
