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 d? (5 points)

(2x + 16) + (6x − 4) = 90

(x + 16) − (x) = 90

(x + 16) + (2x + 16) = 180

(2x + 16) + (x) = 180

Option 4: (2x + 16)° + (x)° = 180°

Step-by-step explanation:

See the attached figure.

For a quadrilateral inscribed in a circle

The opposite angles are supplementary.

So, ∠D + ∠B = 180°

From the figure:

∠B = x°  and ∠D = (2x+16)°

∴  (2x + 16)° + (x)° = 180°
