Quadrilateral OPQR is inscribed in circle N, as shown below. Which of the following could be used to calculate the measure of ∠R
OP?
A:(6x − 4)° + (2x + 16)° = 360°
B: (x + 16)° + (6x − 4)° = 360°
C: (6x − 4)° + (2x + 16)° = 180°
D: (x + 16)° + (6x − 4)° = 180°
A:(6x − 4)° + (2x + 16)° = 360°
B: (x + 16)° + (6x − 4)° = 360°
C: (6x − 4)° + (2x + 16)° = 180°
D: (x + 16)° + (6x − 4)° = 180°
