最终题干渲染（f_body 预览）

已知A, B, C是⊙O上的三个点，且∠AOB = 60°，那么∠ACB的度数是(       ).
A. 30° (B)120° (C)30°或120° (D)30°或150°

答案 / 解析

答案（f_answer）

因为CP是切线, 所以∠OCP = 90°, 即∠OCB+∠BCP = 90°, 因为∠BCP = 35°, 所以∠OBC = ∠OCB = 55°,所以 ∠ABC = ∠ABO + ∠OBC = 75°, 因为四边形ABCD是⊙O的内接四边形，∴∠ADC = 180° −∠ABC = 105°. 15.B ⏜ ⏜ 在⊙O 上取一点 E，连接 BE，CE， ∵OA ⊥BC, OA 是 ⊙O 的半径，所以AC = BA, ∵∠ADC = 25∘, ∴∠E = 2∠ADC = 50∘, ∴∠CAB = 180∘−∠E= 130∘, 故选：B．
