Question

The equation of lines passing
through (L2) and making an
angle 30" with y-axis is​

Answer 1

Answer:

Hope it will be helpful

Step-by-step explanation:

Given that line passing through (1, 2) making an angle 30° with y – axis.

∴ Angle made by the line with x – axis is (90° - 30°) = 60°

∴ Slope of the line, m = tan 60°

= √3

So, the equation of the line passing through the point (x1, y1) and having slope ‘m’ is

y – y1 = m(x – x1)

Here, (x1, y1) = (1, 2) and m = √3

⇒ y – 2 = √3(x – 1)

⇒ y – 2 = √3x - √3

⇒ √3x – y - √3 + 2
