A road sign is in the shape of a regular heptagon. What is the measure of each angle on the sign? Round to the nearest tenth.
lisabon 2012 [21]
<span><u>Answer </u>
A) 〖128.6〗^o

<u>Explanation </u>
The question requires us to find the interior angle of a regular heptagon.
To do this first calculate the exterior angle of that polygon.
The sum of exterior angles is 360o. A heptagon has 7 sides.
So, one exterior angle = 〖360〗^o/7=〖51.4〗^o
interior angle+exterior angle=〖180〗^o
exterior=180-51.4=〖128.6〗^o
