Problem

The line

\frac{x+6}{5} = \frac{y+10}{3} = \frac{z+14}{8}

is the hypotenuse of an isosceles right angled triangle whose opposite vertex is

(7, 2, 4)

. Then which of the following is not the side of the triangle ? a.

\frac{x-7}{2} = \frac{y-2}{-3} = \frac{z-4}{6}

\frac{x-7}{3} = \frac{y-2}{6} = \frac{z-4}{2}

\frac{x-7}{3} = \frac{y-2}{5} = \frac{z-4}{-1}

d. None of these
