For what values of x and y must the figure below be a parallelogram?

x = 8

y = 10

Step-by-step explanation:

10x = 11x - 8

-11x    -11x

-x = -8

-1     -1

x = 8

10y = 100

10       10

y = 10

y=10 and x=8

Step-by-step explanation:

Opposite angles are equal.

10y=100

y=10

10x=11x-8

8=1x

x=8

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.
