Find the perpendicular distance from the point $P(2, 3)$ to the line $3x - 4y + 1 = 0$, and find the distance between the parallel lines $3x - 4y + 1 = 0$ and $3x - 4y - 9 = 0$.

Find the angle between the lines $2x - y + 3 = 0$ and $x - 3y + 2 = 0$. Also find the equations of lines passing through $(1, 2)$ making an angle of $45^\circ$ with the line $2x - y + 3 = 0$.

Find the perpendicular distance from the point $(3, -2)$ to the straight line $5x - 12y + 11 = 0$. Hence find the distance between the parallel lines $5x - 12y + 11 = 0$ and $5x - 12y - 28 = 0$.
