Answer 2

Answer:

OPTION 1 ===> 60°

Step-by-step explanation:

BC = OC (GIVEN)

<CBO = <COB (ANGLE OPP. TO SAME SIDE ARE EQUAL)

SO, <COB = 20°

IN TRIANGLE BCO,

<CBO + <COB + <BCO = 180°

20° + 20° + <BCO = 180°

<BCO = 180° - 40°

<BCO = 140°

NOW, <BCO + <OCD = 180°

140° + <OCD = 180°

<OCD = 180° - 140° = 40°

AGAIN,

OC = OD (RADIUS OF SAME CIRCLE)

<OCD = <ODC (ANGLE OPP. TO SAME SIDE ARE EQUAL)

SO, <ODC = 40°

IN TRIANGLE OCD,

<OCD + <ODC + <COD = 180°

40° + 40° + <COD = 180°

<COD = 180° - 80° = 100°

NOW <COB + <COD + <AOD = 180°

20° + 100° + <AOD = 180°

<AOD = 180° - 120° = 60°

THEREFORE <AOD = 60°
