The equation for finding the line L is that the line L passes through the point (1,0) and the angle between the line L 1: root 3x + y-root 3 = 0 is 30 degrees What do you do when k doesn't exist

The equation for finding the line L is that the line L passes through the point (1,0) and the angle between the line L 1: root 3x + y-root 3 = 0 is 30 degrees What do you do when k doesn't exist

L1: root 3x + y-root 3 = 0 is transformed into y = - root 3x + root 3
The slope of L1 is - root 3
Let the angle between L1 and X axis be a
Tana = - root 3, so a = 120
The angle between L and L1 is 30 degrees
So the slope of L has two cases: Tan (a + 30) and Tan (A-30)
Then Tan (a + 30) = - radical 3 / 3
Tan (A-30) = Tan (90) straight line x = 0 axis
Let the equation of line l be y = KX + B when the line L passes (1,0)
Given the slope, we can find B = root 3 / 3
So the linear equation of L is: radical 3 / 3 + y-radical 3 / 3 = 0
