Which equation could be used to solve for the measure of angle Q? (1 point) Circle N is shown with a quadrilateral OPQR inscribed inside it. Angle O is labeled x degrees. Angle P is labeled y degrees. Angle Q is labeled z degrees. Angle R is labeled w degrees. z + x = 180 z + w + x = 360 z − (w + x) = 360 z + w = 180
