For the polyhedron, use Euler's Formula to find the missing number. faces: edges: 13 vertices: 9 The number of faces is . (Type a whole number.)

A regular polygon has n equal sides and n equal angles. The measure a of an interior angle in degrees is given by a = 180( 1 - 4). Solve for n. n = How many sides does the outdoor bandstand shown below have if the performance platform is a regular polygon with interior angles measuring 120°? sides

Finn is planning to build a small stage for the local theaters upcoming production. Finn is planning the stage in a shape of a regular polygon but doesn’t want the exterior angles at each vertex to be smaller than 65 degrees. If Finn makes the stage a regular hexagon, will the interior angles meet his requirements?
