JEE Main 2020 (Online) 7th January Evening Slot | Straight Lines and Pair of Straight Lines Question 85 | Mathematics

A straight line L at a distance of 4 units from the origin makes positive intercepts on the coordinate axes and the perpendicular from the origin to this line makes an angle of 60^o with the line x + y = 0. Then an equation of the line L is :

x + $$\sqrt 3 $$y = 8

$$\sqrt 3 $$x + y = 8

( $$\sqrt 3 $$ + 1)x + ( $$\sqrt 3 $$ – 1)y = 8 $$\sqrt 2 $$

( $$\sqrt 3 $$ - 1)x + ( $$\sqrt 3 $$ + 1)y = 8 $$\sqrt 2 $$
