Measure of angle between the planes 5x-2y + 3z-7=0 and 15x - 6y+9z+5=0 is

Distance between the lines 5x + 3y-7 = 0 and 15x +9y + 14 = 0 is

If y-3=0,x-3y+9=0 and 3x-2y+1=0x+y-3=0,x-3y+9=0 and 3x-2y+1=0 are sides of triangle then area of triangle.

solve for x and y 2x-3y+7=0 3x+4y-5=0

The angle between the lines 5x+3y-7=0\ a n d\ 15 x+9y+14=0 is a. 0^0 b. 60^0 c. 45^0 d. 30^0

The angle between the lines 5x+3y-7=0\ a n d\ 15 x+9y+14=0 is 90^0 b. 60^0 c. 45^0 d. 30^0

Given the four lines with the equations x+2y-3=0 , 3x+4y-7=0 , 2x+3y-4=0 , 4x+5y-6=0 , then
