Find the equation of a straight line on ...

Find the equation of a straight line on which length of perpendicular from the origin is four units and the line makes an angle of 120° with the positive direction of X -axis.
Thinking Process : Equation of line which makes an angle `alpha` with positive side of X axis and whose length of perpendicular from origin `p` is given by `x cos alpha+ y sin alpha = p`.

Text Solution

Verified by Experts

The correct Answer is:
`sqrt( 3) + y =8`,
which is required equation of line.
