The slope of the line through the origin which makes an angle of 30^ with the positive direction of Y -axis measured anticlockwise is

Options

  1. A-2 3
  2. B- 3
  3. C3 2
  4. D-1 3

Correct answer

B. - 3

Step-by-step solution

Refer figure Angle made by line L with positive direction of X axis is (90^ +30^ ) i.e. 120^ . Slope of line L = (120^ )= ( -60^ )=- 60^ =- 3
