WebThe measure of each exterior angle= 360°/n = 360°/11 ≈ 32.73° Example 3: The exterior angles of a polygon are; 7x°, 5x°, x°, 4x° and x°. Determine the value of x. Solution Sum of exterior =360° 7x° + 5x° + x° + 4x° + x° =360° Simplify. 18x = 360° Divide both sides by 18. x = 360°/18 x = 20° Therefore, the value of x is 20°. Example 4 Web10 jun. 2024 · The measure of each exterior angle of a regular polygon of 18 sides is 20 degrees. We know that the measure of each exterior angle of a regular polygon is 360o/n. So, 360o / 18 = 20 degrees. What is the measure each exterior angle of a regular polygon having 180 sides? The answer is 180° – 72° = 108°. WebIn Euclidean geometry, an angle is the figure formed by two rays, called the sides of the angle, sharing a common endpoint, called the vertex of the angle. Angles formed by two rays lie in the plane that contains the rays. Angles are also formed by the intersection of two planes. These are called dihedral angles.Two intersecting curves may also define an … probuild bend oregon
