Let $$P_{1}:2x+y-z=3$$ and $$P_{2}:x+2y+z=2$$be two planes. Then, which of the following statement(s) is (are) TRUE?

The line of intersection of $$𝑃_{1}and 𝑃_{2}$$ has direction ratios 1, 2, −1

The line $$\frac{3x-4}{9}=\frac{1-3y}{9}=\frac{Z}{3}$$ is perpendicular to the line of intersection of $$𝑃_{1} and 𝑃_{2}$$

The acute angle between $$P_{1} and P_{2}$$ is $$60^\circ$$

If $$P_{3}$$ is the plane passing through the point (4, 2, −2) and perpendicular to the line of intersection of $$𝑃_{1} and 𝑃_{2}$$, then the distance of the point (2, 1, 1) from the plane $$P_{3}$$ is $$\frac{2}{\sqrt{3}}$$
