Given:
Equation passes through (0,0) and make an angle of 75° with the line x + y + √3(y - x) = a.
To find:
Equation of given line
Explanation:
We know that the equations of two lines passing through a point x1,y1 and making an angleα with the given line y = mx + c are
y - y1 = \(\frac {m±\,tan\ \,\alpha}{1±m\,tan\ \,\alpha}\) (x - x1)
Here, Equation of the given line is,
Comparing this equation with y = mx + c
We get,
and tan75∘ = 2 + √3
So, the equations of the required lines are
Hence, Equation of given line is x = 0 and √3x +y = 0
