How do I do number 16?

 x = 121 degrees

Step-by-step explanation:

(n-2) x 180

(6-2) x 180

4 x 180=720

599 +x = 720

599 - 599 = x  +x = 720 - 599 = 121

and then add up all the degrees

88 + 105 + 142 + 140 + 124 + 121 = 720

so there for you answer for x is 121 degrees

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.

a; x = 0.5

step-by-step explanation:
