find the image of the line x-1/3=y-3/1=z-4/(-4) in the plane 2x-y+z+3=0 is ?

This is urgent nd I want the equation of the line

theta = l/rwhere l = arc length , r = radius , theta = centraal angle.In this formula , theta will always be calculated in radians or degree ?

Find the vector and Cartesian equations of the plane containing the two lines:

r=2i+j-3k+U(i+2j+5k) and r= 3i +3j+2k+T(3i-2j+5k)

find the equation of the plane through the line of intersection of the planes x+Y+Z=1 and 2x+3Y+4Z=5 which is perpendicular to the plane x-Y+Z=0.also find the distance of the plane obtained above ,from the origin
