2 lines intersect to form 4 angles. Clockwise, from top left, the angles are: x degrees, 105 degrees, z degrees, y degrees. Which equations are true for the values of x, y, and z in the figure? Select all that apply.
x° + 105° = 180°
x° = z°
105° – y° = 90°
x° + y° + z° = 180°
180° – z° = y°
x° + y° = 105°
