Rotation through 90° counterclockwise has the mapping.

(x \: ,\: y)  \:  \rightarrow( - y \: ,\:  \: x)
A(2 \:  \:,5) \:  \rightarrow \: A' ( - 5 \:  \:,2)

B(2 \:  , 2) \:  \rightarrow B'( - 2 \: , \: 2)

C(4 ,\:  \: 3) \:  \rightarrow C'( - 3, \:  \: 4)

D(4 ,\:  \: 6) \:  \rightarrow D' ( - 6, \:  \: 4)

ABCD is a quadrilateral inscribed in a circle, as shown below: Circle O is shown with a quadrilateral ABCD inscribed inside it.
kogti [31]

Answer:

B. (x + 16) + (6x − 4) = 180

Step-by-step explanation:

The Cyclic Quadrilateral Theorem states that for a quadrilateral in a circle, the opposite angles will equal 180 degrees. So therefore you can conclude:

∠A + ∠C = 180° which would be (x + 16) + (6x - 4) = 180°

∠B + ∠D =180° which would be x + (2x - 16) = 180°
