C. (2x + 16) + (x) = 180°
Step-by-step explanation:
See attachment for the cyclic quadrilateral
One theorem of cyclic quadrilateral states that; opposite angles = 180°
In the attachment, the angle opposite B is D
Where B = x
D = 2x + 16
From the theorem stated above;
B + D = 180°
Substitute the values of B and D in the formula above
x + 2x + 16 = 180
From the list of given options, the correct answer is C
