ABCD is a quadrilateral inscribed in a circle, as shown below: Circle O is shown with a quadrilateral ABCD inscribed inside it. Angle A is labeled x plus 16. Angle B is labeled x degrees. An

What equation can be used to solve for angle A? (5 points)

(x + 16) + (6x − 4) = 180
(x + 16) + (x) = 90
(x + 16) − (x) = 90
(x + 16) − (2x + 16) = 180
