Cos 57 it has to add up to 90
By definition, the equation of a circle, centered at point (a, b) is

Where r is the radius of the circumference, and is calculated as the distance from the center to any point belonging to the circumference.
We have the center (5, -4) and the point through which the circumference passes (-3, 2), then:

Finally, the equation of the circumference is:

Dude you distribute.3(x+3)
That equals.3x+.9!!!!
45÷5 is 9 so that means joe has only 9 marbles
