Answer:
20
Step-by-step explanation:
One angle of a nonagon has an angle of 140 degrees, so
7x = 140.
Divide 140 by 7 to find the value of x.
140 ÷ 7 = 20
The horizontal axis is the X-axis and the vertical axis is the Y-axis
<h3>Answer</h3>
0.16666666666... (it's periodic)
<h3>Explanation</h3>
P(3)= 1/6 = 0.1666666666
Now round as needed
I believe the answer is 0.53
It states that if you place two angles side by side, then the measure of the resulting angle will be equal to the sum of the two original angle measures.
