Answer: The figure is a regular hexagon.
Step-by-step explanation:
Answer:hexagon
Step-by-step explanation:
Each interior angle=120
Each interior angle in a polygon=180(n-2)/n
120=180(n-2)/n
Cross multiply
120n=180(n-2)
120n=180n-360
Collect like terms
180n-120n=360
60n=360
Divide both sides by 60
60n/60=360/60
n=6
the polygon has 6 sides which means that it is an hexagon

1 mile is 1760 yards
1 min is 3600 seconds
then you treat the units as variables and solve. I hope I did this right heh...
x^2+x=132
x=11
im sorry I cant explain how I got the answer aside from saying 10*10=100 100+10 is 110 so I was like lets try 11
6/x = 8
6 = 8x
8x = 6
x = 6/8
x = 3/4
x = 0.75
