18 because that’s the greatest common factor for all of them
1/3x>-2=1>3x.-2
=1>-6x
=-1/6>x
I divided 315 by any random number and chose the one that gave me a whole number
So I got
x
9 because 24 divided by 2 is 12 and 12 subtracted by 3 is 9
The area of a polygon equals
area = circumradius² * number of sides * sin (360 / # of sides) / 2
area = 77² * 20 * sin (360 / 20) / 2
area = 77² * 20 * sin (18) / 2
area = 118,580 * 0.30902 / 2
area =
