Answers (1)

Answer:

-6

Hint:

Use direction ratios

Given:

$\frac{x-2}{3}=\frac{y-1}{-5}=\frac{z+2}{2}$

Solution:

The line is

$\frac{x-2}{3}=\frac{y-1}{-5}=\frac{z+2}{2}$

The direction radius of the line are(3,-5,2)

As the line lies in the plane x + 3y - αz + 7 = 0

We have $3-15-2\alpha+7=0\Rightarrow -2\alpha-5=0$

$\\ \\ \alpha=-\frac{5}{2}$
