540+25=565
(1) 30,489.3 repeating
(2) 70,282
(3) 50,505
Answer:
y+2=3(x+1)
Step-by-step explanation:
y-y1=m(x-x1)
m=(y2-y1)/(x2-x1)
m=(7-(-2))/(2-(-1))
m=(7+2)/(2+1)
m=9/3
m=3
y-(-2)=3(x-(-1))
y+2=3(x+1)
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 .
