<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

Answer:
x-12≤7
x≤19
Step-by-step explanation:
less than means it comes after
x-12
is at most means less than or equal to
x-12≤7
Add 12 to each side
x-12+12≤7+12
x≤19
