Circle in Triangle
Hi I have attached the question as a word file. I have worked through it, and need help with the last bit.
I do not understand how to show the relationship between A and B in ii)
he first time I did the question, I tried to use the relationship to evaluate the areas asked for next, which ended up being confusing.
However, this time, I just worked with the kite and sector of the circle to find A. I didn't use B at all.
Since B was given right before the question to work out the final 2 Areas was asked, I am presuming that it can be used to work out the answers, or else it would have no reason of being added.
So basically, I dont understand the relationship, and also, can anyone show how they would do the last part using this relationship between area A and B?
Thanks Grandad. I was told I had to mention something like:

Also, I wanted to try the relationship with B to work out the Area of A just to experiment around. But this didnt work out.
A(pi/3) = B(pi/6) = 2*AreaQCR - Area segment
= root3 - 5pi/12
rather than the pi/3...
I get pi/3 if I take the angle ORP to be pi/3, not pi/6
