A(-7,-4) B(-2,0)
√[(x'-x)^2+(y'-y)^2]
√(-2-(-7)^2+(0-(-4)^2
√(5^2)+(4^2)
√25+16
√41
the distance is approximately 6.4 units
Well each piece of the whole is what made the whole... so in that case each piece is little 1/4's of the whole....
The answer is =324°*(\pi )/(180<span>°</span>)

In this case, the pattern is the number, in this case, 3, multiplied by the number below it.
See?

Hope this helped :)
