The equation of a line, whose perpendicular distance from the origin is 5 units and the angle, which the perpendicular to the line from the origin makes, is 210^ with positive X -axis, is

Options

  1. A-x 3 +y+10=0
  2. Bx 3 +y-10=0
  3. Cx 3 +y+10=0
  4. Dx 3 -y+10=0

Correct answer

C. x 3 +y+10=0

Step-by-step solution

Here, P=5 and =210^ Writing the equation of straight line in normal form aligned & x (210^ )+y 30^ =5 & -x 30^ -y 30^ =5 & -x 3 2 -y 1 2 =5 & - 3 x-y=10 & 3 x+y+10=0 aligned
