3D Geometry · Points on line at given distance

Let a triangle

PQR

be such that

P

and

Q

lie on the line

\dfrac{x+3}{8} = \dfrac{y-4}{2} = \dfrac{z+1}{2}

and are at a distance of 6 units from

R(1, 2, 3)

. If

(\alpha, \beta, \gamma)

is the centroid of

\Delta PQR

, then

\alpha + \beta + \gamma

is equal to:
