Answer:
m(slope)=0
Step-by-step explanation:
To find slope given two points, use the formula m = y2 - y1/x2 - x1
(-10) - (-10)/(-3) - 5
0/-8
Anything being divided from 0, or divided by 0 is always 0, so the slope is 0.
Hope this helps.
I believe its c i might be wrong
A polygon is regular when all angles are equal and all sides are equal (otherwise it is "irregular"). This is a regular pentagon (a 5-sided polygon)
20 degrees. i have a protractor, and its really helpful! you should use one.
