Yup,thanks but the ms stated b) (i) Angle in a semicircle oe thats why i was confused.
ABCD is a sq. that means its diagonals are equal, they will intersect at the centre of circle. this makes AC the diameter. and any angle extended from diameter is right angle.
but mine was also right right?

Yup...how did were u able to figure it out ,I mean of course u used the vector concept ,any other concept?

So you don't know the explanation?

Well, i already had an idea how to solve this question. But i kept thinking it was something related to vectors. I spent like 2 hours thinking about a vector-related way to solve this, and in the end, came back to my original hypothesis, and used similarity to find this ratio. But i didn't give up, and only left the question when i had found a solution. :)

I know the solution and explanation.I am asking u whether u arrived at the answer with the same method or not.Jees.yar kabhi explanation ka baghair is tarah ka question naho ho sakta coz it involves a lot of steps using the similarity method to find the answer.
And yeah well done self stated "biggest loser in the world" :p U rock!

Ruk ja....Maths P2 tyar karo..no anyone cud not have done it in the time u took...Time factor may only eventually help u to piece together the different stages req to find the answer and pave a path but the original ideas are wht u have to think of in the first place

ABCD is a sq. that means its diagonals are equal, they will intersect at the centre of circle. this makes AC the diameter. and any angle extended from diameter is right angle.
another explanation to this is, the fact that angles extended from line AC ( angle ABC, and ADC) are right angles makes AC the diameter of circle. so any other angle from AC will also be a right angle.
