Question

AB passes through centre O of the circle. Angle BAC = 20 Degree, find Angle AOC​

Answer 1

Answer:

Given,

AB passes through the centre of the circle which means it is the diameter of the circle

Therefore,

BOC + AOC = 180°

20° + AOC = 180°

AOC = 180°-- 20°

AOC = 160°

So,Angle AOC = 160°

Answer 2

Answer:

AOC = 160°

Step-by-step explanation:

BAC + AOC = 180°

20 + AOC = 180°

AOC = 180 - 20

AOC = 160°
