Because the nonagon is regular, the angles are equal. Nona means nine. The total of the measures of the interior angles of any polygon is (n-2)180. Use this formula to find the measure of one interior angle.
(9-2)180
7*180=1260. Divide by 9 to get the measure of one angle.
1260/9=140
The answer is 140 :)
Answer:
D
Step-by-step explanation:
Given
4x + 8.2 ≤ 32.2 ( subtract 8.2 from both sides )
4x ≤ 24 ( divide both sides by 4 )
x ≤ 6 → D
Answer: I think it would be 285.
Step-by-step explanation:
A circle is 360* so I did 360-75. Hope this helps!!!
18 square units should be the right answer
