Answer:
1. 360°
2. (n-2) x 180°
3. 30m
4. (n-2) × 180° (una)
5. 1260°
Step-by-step explanation:
1. Since each exterior angle and interior angle form a linear pair, one exterior angle of a decagon = 180 - 144 = 36°. We know that a decagon had 10 exterior angles, so, 10 × 36 = 360°.
2. The sum of the measures of the interior angles of an octagon =(8−2)180° . The sum of the measures of the interior angles of an octagon is 1080°.
3. Hexagon has 6 sides. X it to 5m and get the correct answer.
4. Sum of Interior Angles in a Pentagon. We know that the sum of the interior angles of a polygon of n sides = (n – 2) × 180°. = 3× 180°= 540°. Hence, the sum of interior angles of a pentagon is 540°.
5. A nonagon in which all sides are equal and all angles are equal is a regular nonagon. Each angle of a regular nonagon is of 140°. A nonagon in which all sides are not equal and all angles are not equal. The measure of its angles are different but total sum of all its interior angles is always 1260°.
pa brainliest po sure ako sa answer:) ;)
