300. 30˚ n = sides 8. Measure of each exterior angle = 360°/n = 360°/3 = 120° Exterior angle of a Pentagon: n = 5. 45˚ n = sides 2. Solution: We know that the sum of exterior angles of a polygon is 360 degrees. measure of each exterior angle =360°/n ,where n is the number of sides/angles. 36˚ n = sides 4. The sum of the exterior angles of a polygon is 360°. 18˚ n = sides exterior angle interior angle Measure of a Single Exterior Angle. The sum of the interior angles of a nonagon is... 1260 degrees. 90˚ n = sides 9. 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. 60˚ n = sides 10. Find the number of sides of a regular polygon with an exterior angle of: 1. If the side of a polygon is extended, the angle formed outside the polygon is the exterior angle. 72˚ n = sides 5. 200. Answer: the polygon name is decagon . Step-by-step explanation: sum exterior angles is 360 . exterior angle = 36, so interior angle = 144 180(n-2) = 144 x n 180n - 360 = 144n 180n - 144n = 360 36n = 360 36n/36 = 360/36 n = 10 Thus, there are 10 sides to the polygon … 300. Thus, 70° + 60° + 65° + 40° + x = 360° 235° + x = 360° X = 360° – 235° = 125° Example 2: Identify the type of regular polygon whose exterior angle measures 120 degrees. The sum of the exterior angles is 10 x 36 = 360 degrees. The sum of the exterior angles of a 36-gon is... 360 degrees. 10 sides . A decagon has 10 sides so its interior angles add up to 180(10) - 360 = 1440 degrees. What makes a polygon regular? One important property about a regular polygon’s exterior angles is that the sum of the measures of the exterior angles of a polygon is always 360°. All sides and angles are congruent. Since, we know that, the sum of measures of exterior angles of a polygon is 360°, i.e. Hence, 22° can never be the measure of exterior angle of a regular polygon. Each exterior angle in a regular polygon has measure 360/n degrees where n = the number of sides. 1 degree. Thus, measure of each exterior angle will always divide 360° completely. 200. 20˚ n = sides 6. Since the regular polygon has an exterior angle of 36 degrees then there are 10 sides since 360/10 = 36. What is the measure of one exterior angle of a polygon with 360 sides? Exterior angles of polygons. 360÷10=36 200. Now your interior angle and exterior angle with the line extended add to equal to 180 degrees since the line drawn is a straight line. Formula for sum of exterior angles: The sum of the measures of the exterior angles of a polygon, one at each vertex, is 360°. Examples. 15˚ n = sides 7. Substitute. Therefore, on average, each interior angle is 144 degrees and each exterior angle is 36 degrees. 24˚ n = sides 3. Find the measure of angle 2. Exterior angle of a triangle: For a triangle, n = 3. 72 degrees. For example, an eight-sided regular polygon , an octagon, has exterior angles that are 45 degrees each, because 360/8 = 45.
