Question

Given:AB is the diameter
< BOC=35%
find m <AOC.​

Answer 1

Step-by-step explanation:

Given,

AB is a diameter of a circle with the centre O and CD BA

∠BAC=20

o

Now,

(i)we know that the angle at the centre is twice the angle at the circumference subtended by the same arc.

Therefore,

∠BAC=20

o

∠BOC=20
