HELP ME ASAP Triangel congruency maze activity

Step-by-step explanation:

the sum of all the angles in a triangle are equal to 180

so you can add   the 3 given angles together to equal 180:

5y + 2y + 2y = 180

or since all three angles have the same letter, combine the 3 angles to equal 180:

9y = 180

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.
