For a cyclic quadrilateral, opposite angles total up to 180 degrees. in the case of quadrilateral opqr, angles o and q are opposites (as are angles p & r), so these sum up to 180. angle o = x + 16, while angle q = 6x - 4. therefore their sum is 180: (x + 16) + (6x - 4) = 180this is the fourth choice.
