Find the diameter of the crcle that passes through A, B and C.
Could someone please explain to me how to do this? Any hints?
First draw a proper diagram showing the circle, the centre and a few other auxillary lines. Then fill in what you know on the diagram.
See the attachment (P is the foot of the perpendicular from O onto AC). Can you explain all the values in this diagram?
You should be able to find the diameter of the circle easily once you use the sine rule to find the length of AC.
