Given that ∠MQL = 180° and ∠XQR = 180°, which equation could be used to solve problems involving the relationships between ∠XQL and ∠MQR?

Responses
A (146 − 4b) = (122 − 1b)(146 − 4b) = (122 − 1b)
B (146 − 4b) + (122 − 1b) = 180(146 − 4b) + (122 − 1b) = 180
C (146 − 4b) − (122 − 1b) = 180(146 − 4b) − (122 − 1b) = 180
D (122 − 1b) − 180 = (146 − 4b)(122 − 1b) − 180 = (146 − 4b)
E (122 − 1b) − 360 = (146 − 4b)

B (146 − 4b) + (122 − 1b) = 180
