A regular n-gon has n lines of symmetry
The angle of rotational symmetry for regular n-gon is 360 / n degrees.
Answer:
m∠1 = 94°
m∠2 = 43°
m∠3 = 50°
m∠4 = 50°
m∠5 = 130°
m∠6 = 130°
Step-by-step explanation:
To find this, you have to find your slope with the given x and y values first. Use the equation Y2-Y1/X2-X1 for finding the slope.
4-1/3- -6
3/9= 1/3
Now you know your slope is 1/3, and you can basically assume your third answer listed is correct since none of the other ones contain a positive 1/3 but I will explain how to continue for future use. Next you can use one set of x and y values to plug into the equation y=mx+b, and plug in 1/3 for m as well.
4=1/3(3) + b
4 = 1 + b
-1 -1
3 = b
Now you have your y intercept and your slope, so you can make your equation.
Y= 1/3x + 3
We can simply divide 5.5 by 10 to find the unit price.
5.5/10 = 0.55
