1. The problem statement, all variables and given/known data Sketch the loci, find centre point and the radius of the circle. args((z-3i)/((z+4))=π/6 2. Relevant equations args(x/y)=args(x)-args(y) Circle theorem - inclined angle theorem 3. The attempt at a solution I sketched the circle with major arc. Radius= using Pythagorus I got the radius as 5 unit^2 . H=O/sinθ . H=2.5/sin(π/6) I am stuck on finding the centre point.
