For the straight line 4x + 3y - 6 = 0 and 5x + 12y + 9 = 0 , find the equation of the bisector of the obtuse angle between them.

The line x+y=3 meets the circle x^2+y^2-4x+6y-3=0 at A and B . A variable line meets the axes at P and Q respectively so that AQ meets BP at R at a right angle. Show that the locus of R is x^2+y^2-8x+2y+9=0

In the given figure l and m are parallel lines and t is a transversal such that angle1=135^(@) find the measure of each one of the angels angle2,angle3,angle4,angle5,angle6,angle7. AND angle8

(i) Find the value of 'p' so that the lines : l_(1) : (1 - x)/(3) = (7y -14)/(2p) = (z - 3)/(2) and l_(2) : (7 -7x)/(3p) = (y - 5)/(1) = (6 - z)/(5) are at right angles. Also, find the equations of the line passing through (3,2, -4) and parallel to line l_(1) . (ii) Find 'k' so that the lines : (x - 3)/(2) = (y + 1)/(3 ) = (z - 2)/(2k) and (x + 2)/(1) = (4 -y)/(k) = (z + 5)/(1) are perpendicular to each other.
