2nd question can also be solved by joining EO where O is the centre of the circle, and using triangle EOC. however the time taken would be same.
thanks a lot for writing such informative and useful blogs.
In the first question,
if we consider sum of angles in a straight line , i.e angle AOD+angle AOB+ angle BOC =180, im getting x=y?
Can you please tell, what is the mistake im making?
I am not sure how you are getting that, actually. AOD is x, AOB is (180 – 4y) and BOC is y, which gives us x = 3y only! Could you recheck your numbers?
answer of first question i am getting is (3)1…….whats the actual answer as you mentioned that students considered that exterior angle mistakenly then how can the answer be (1)3…confused!!!!

@Pratskool: True, there too we would use the same theorem 🙂 Thanks…
