Polygon with exterior angle of 30
Did you know?
WebSep 26, 2012 · The total interior angle of a 12 sided polygon is = (12 - 2) 180 degrees = 1800 degrees. The internal angle at each vertex of an regular dodecagon is equal to = = 150 degrees. While the exterior angle at a single vertex is = = 30 degrees. The total exterior angle of a 12 sided polygon is 360 degrees. WebThe sum of all the exterior angles of a polygon is always 360 degrees. From the given ratio, we can formulate an equation: x+2x+3x+4x+5x = 360. 15x = 360. x = 24. As x=24, the measure of each of the exterior angles would be …
WebSince the sum of exterior angles of any polygon is always equal to 360°, we can divide by the number of sides of the regular polygon to get the measure of the individual angles. For example, for a pentagon, we have to divide 360° by 5: 360°÷5 = 72°. Each exterior angle in a regular pentagon measures 72°. In the following table, we can see ... WebExterior Angles of Polygons The Exterior Angle is the angle between any side of a shape, and a line extended from the next side. Another example: When we add up the Interior …
WebFeb 1, 2010 · How many sides does a regular polygon have if its exterior angles are 30 degrees? A regular polygon with exterior angles of 30 degrees has: 360/30 = 12 sides.
WebTherefore, all its exterior angles measure the same as well, that is, 120 degrees. Since the sum of exterior angles is 360 degrees and each one measures 120 degrees, we have, …

Remark 1: A discussion should take place about the sidelengths of the polygon, for which there is a ... simply home loans llcWebHow many sides does a polygon with an exterior angle of 30 have? Since all the angles are congruent, 30a=360, and a=12. Since a=s, s=12, so the polygon has 12 sides. What is the sum of a 12 sided polygon? Dodecagon is a 12-sided polygon with 12 angles and 12 vertices. The sum of the interior angles of a dodecagon is 1800°. simply home lending fayettevilleWebAs you can see, for regular polygons all the exterior angles are the same, and like all polygons they add to 360° (see note below). So each exterior angle is 360 divided by the n, the number of sides. As a demonstration of this, drag any vertex towards the center of the polygon. You will see that the angles combine to a full 360° circle. simply home loansWeb2 Answers. The Dragon answered. The sum of exterior angles of any polygon is 360 degrees.
