we have:

x + 4 + x + 6 + x + 2 + x + 18 + x = 180.3

<=> 5x + 30 = 540

<=> 5x = 520

<=> x = 104

we also have: m<5 + x = 180

<=> m<5 = 180 - 104

<=> m<5 = 76

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.
