Which equations are true for the values of x, y, and z? Select three options.

2 lines intersect to form 4 angles. Clockwise, from top, the angles are: 65 degrees, x, y, z.
x degrees + 65 degrees = 180 degrees
x degrees = z degrees
y degrees = 65 degrees
x degrees= 65 degrees
x degrees + y degrees + z degrees = 115 degrees
