Can anyone help me with math

just 2 and show me how u did it

point a is the center of the circle that passes through points e, f, and g and the center of the circle that passes through points x, y, and z.

arc length = radius * x ( in radians)

6 * pi = 18 * x

divide by 18 on each side

6 pi / 18 = x

pi/3 = x

the angle is pi / 3 radians

or   60 degrees

this seams to be a multiple choice question, state the options below.
