Answer:
x2
Step-by-step explanation:
<span>The sum of the interior angles of any regular polygon is (n - 2) X 180
30 = n
</span><span>[(30) - 2] × 180
</span>28 X 180
5040
<span>The interior angle of a regular polygon = the sum of interior angles ÷ number of sides</span>
5040 <span>÷ 30 = 168</span>
Therefore the measure of each interior angle in a regular 30-sided polygon is 168°
Answer:
Option C
Step-by-step explanation:
Do solve this you use PEMDAS. This stands for:
Parenthesis
Exponents
Multiplication
Division
Addition
Subtraction
Because there are no parentheses or exponents in this equation, we go straight to the division.
1) 8 divided by 4 equals two so we rewrite the equation. 5+6 x 2 - 2 + 7.
2) Next in order of pemdas is multiplication. Yes I know that in pemdas multiplication does come before division but it doesn’t matter in this problem which you do first. So now we do 6 x2 =12. We then rewrite the equation 5+12-2+7.
3) lastly, addition and subtraction are grouped together and you can just do it in order of the problem. So we do 5+12=17. 17-2=15. And 15+7=22.
So the final answer is: 22
