Let √3i + j,i + √3j and βi + (1-β)j respectively be the position vectors of the points A, B and C with respect to the origin O.

The distance of C from the bisector of the acute angle between OA and OB is 3√2, then the sum of all possible values of b is​ given by,

From given, we have,

y - 1=\dfrac{1}{\sqrt 3}(x-\sqrt 3)

\sqrt 3 y - \sqrt 3 = x -\sqrt 3

x- \sqrt 3 y =0

y - \sqrt 3 = \sqrt 3 (x-1)

y -\sqrt 3 = \sqrt 3 (x-1)

\sqrt 3 x - y = 0

\dfrac{x-\sqrt 3 y}{2} = \pm \dfrac{\sqrt 3x-y}{2}

x-\sqrt 3 x = \sqrt 3 y -y

x(1-\sqrt 3) = - y(1-\sqrt 3)

x + y = 0

x - y = 0

\dfrac{|\beta - (1-\beta)|}{\sqrt 2} = \dfrac{3}{\sqrt 2}

|2\beta - 1|}= 3

\beta = -1,2

-1 + 2 = 1

The sum of all possible values of b is​ 1.
