Answer:
the answer is 4
Step-by-step explanation:
First draw six of anything take out one
It will be easier to explain how to solve this question in a square. If you rotate 4-sided square from the centre, you need to rotate it 90 degrees. The formula for this would be: 360 ° /the side count. In a square, it would be 360° /4= 90°.
In 18-sided polygon, the calculation would be: 360°/ 18 side= 20°
Just subsitute values for x and get values for y
(x,y)
(0,-2)
(1,1)
(-1,-5)
(-2,-8)
here is the graph
