Answer:
<em>The polygon has 9 sides (a regular nonagon).</em>
Step-by-step explanation:
<u>Angles in a Regular Polygon</u>
A polygon with n sides has a total sum of internal angles equal to 180°(n-2). This means that each angle (in a regular polygon) measures
The regular polygon used by Dina for the logo is such that each interior angle measures 140°, thus:
Multiply by n:
Operate:
Reducing:
Solving:
n=9
The polygon has 9 sides (a regular nonagon).
okay so the little 2 above the 3 is called Exponents and its and easier way of multiplication. So in pemdas there would be parentheses then Exponents ect. so Exponents is after parenthesis.
3x2x2=12
12+ the amount of 1x2
1x2= 2 so
12+2=14
