In a decagon, which has 10 sides, the sum of its interior angles is calculated using the formula (n-2) × 180°, where n is the number of sides. For a decagon, this results in a total of 1,440°. An obtuse angle is defined as an angle greater than 90°, and in a regular decagon, all interior angles are equal to 144°. Therefore, all 10 angles in a regular decagon are obtuse.
