M2 CH7: Quadrilaterals and Other Polygons

Find the measure of each interior angle and each exterior angle of a regular 30-gon.

Use the Polygon Interior Angles Theorem to find the measures of the polygons below. Use it to find the missing angle measure. (Hint: start with (n - 2) * 180°)

Use the Exterior Angles Theorem to find the value of x.
