Question

1. Find the exterior angle of a regular polygon with 12 sides.
2. Size of each interior angle of a regular decagon is​

Answer 1

Answer:

1.For a regular n -gon, the measure of an exterior angle is 360˚n . Since a dodecagon has 12 sides, an exterior angles is 360˚12=30˚ .

2.A regular decagon has all sides of equal length and each internal angle will always be equal to 144°.

Answer 2

Step-by-step explanation:

(1) for a regular no-gon, the measure of an exterior angle is 360°n. since a dodecagon has 12 sides, an exterior angle is 360°12=30

(2) A rugural decagon has all side of equal length and each internal angle will always be equal to 144°.
