Question

The length of perpendicular drawn from point (2, 5, 7) on line `x/1 = y/0 = z/0` is ______.

Options

• 2

• 5

• `sqrt74`

• `sqrt78`

Answer 1

The length of perpendicular drawn from point (2, 5, 7) on line `x/1 = y/0 = z/0` is `underlinebbsqrt74`.

Explanation:

Line is `x/1 = y/0 = z/0`, so it passes through the origin with direction vector (1, 0, 0).

Distance from the point (2, 5, 7) to the line is `sqrt(5^2 + 7^2) = sqrt74`
