Find the length of AB if $$\angle YBC = \angle CAX = \angle YOX = 90$$.
I. Radius of the arc is given.
II. OA = 5
Only statement A: Angles OAC, ACB, CBO are right angles => OACB is a rectangle. OC = AB and OC is radius => AB is equal to radius. Hence, we can find the answer using statement A only.
Only statement B: The point B can change even though the point A s fixed at a distance of 5 units on x-axis from origin. Hence, length of AB changes => We cannot find the answer using statement B only.
