How do you find the exterior angle of a decagon?

A decagon has 10 sides so its interior angles add up to 180(10) – 360 = 1440 degrees. Therefore, on average, each interior angle is 144 degrees and each exterior angle is 36 degrees. The sum of the exterior angles is 10 x 36 = 360 degrees.Click to see full answer. Regarding this, what’s the…

A decagon has 10 sides so its interior angles add up to 180(10) – 360 = 1440 degrees. Therefore, on average, each interior angle is 144 degrees and each exterior angle is 36 degrees. The sum of the exterior angles is 10 x 36 = 360 degrees.Click to see full answer. Regarding this, what’s the exterior angle of a decagon?The regular, convex decagon is a subtle and elegant shape, with 10 exterior angles of 36° , 10 interior angles of 144° , and 10 vertices (intersections of sides).Also Know, what is the exterior angle of a 12 sided polygon? Finding Angles and Perimeter of a Regular Dodecagon So, divide 360° by the dodecagon’s twelve exterior angles. Each exterior angle is 30°. Furthermore, how do you find exterior angles? To find the value of a given exterior angle of a regular polygon, simply divide 360 by the number of sides or angles that the polygon has. For example, an eight-sided regular polygon, an octagon, has exterior angles that are 45 degrees each, because 360/8 = 45.What is the sum of all interior angles of a decagon? 1440°
