Represent Jacey wrote an equation to
find an angle measure. What do a and b
stand for in Jacey's equation?
360° divided by a=b

Her we know that Jacey wrote an equation to  find an angle measure. The equation is as follows:

So, if the angle 360° is a central angle, that is, an angle between two radii in a circle, then:

a: Represents the number of equal parts parts the circle is divided

b: Represents the measure of the central angle of each part

For example, suppose you have a circle and want to divide it into six parts, then, the central angle of each part of the circle will measure 60 degrees as indicated in the figure below.
