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°
