86? I'm not sure, sorry.
I plugged in the x and y values of the point given
Step-by-step explanation:
Each interior angle=140°
(n-2)180°/n=140°
180°n-360°/n=140°
180°n-360°=140°n
180°-140°=360°
40°n=360°
n=360°/40°
n=9
Hence, the number of sides of the polygon is 9.
It is nonagon .
Answer:
slope = -1
Step-by-step explanation:
y2-y1 divided by x2-x1
3-7= -4
2-(-2) = 4
-4 divided by 4 = -1
Please list the answer options. I can solve but I need the answer options.
