Answer 1

Step-by-step explanation:

(1) since AB is side of a hexagon, angle AOB = 60°

(2) and AC is side of a eight sided polygon AOC = 45°

(3) BOC = 60° + 45° = 105°

(4) OBC + OCB + BOC = 180°

but OBC = OCB [ OC = OB radii ]

therefore 2OBC + 105° = 180°

2OBC = 180 - 105 = 75°

OBC = 75°/2 => 37.5°
