Question

ABCD is a quadrilateral inscribed in a circle:

Circle O is shown with a quadrilateral ABCD inscribed inside it. Angle A is labeled x plus 16. Angle B is labeled x degrees. Angle C is labeled 6x minus 4. Angle D is labeled 2x plus 16.

What equation can be used to solve for angle D?

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