Answer:

126°

Step-by-step explanation:

∠LQX = ∠MQR

⇒90 - 12b = -3b + 63

⇒ 90 -63 = -3b + 12b

⇒ 27 = 9b

⇒ 27 / 9 = b

⇒ b = 3

∠LQR + ∠LQX = 180°     ( supplementary angles)

⇒ ∠LQR + 90 - 12b = 180°            

⇒ ∠LQR + 90 - 12 x 3 = 180°  

⇒∠LQR + 90 - 36 = 180°  

⇒∠LQR + 54° = 180°    

⇒ ∠LQR = 180° - 54°

⇒ ∠LQR = 126°

option A
