Answer» Correct Answer - A The given lines are `y=(2-sqrt(3))x+5` and `y=(2+sqrt(3))x-7` Therefore, slope of first line `m_(1)=2-sqrt(3)` and slope of second line `m_(2)=2+sqrt(3)` `:. tan theta=|(m_(2)-m_(1))/(1+m_(1)m_(2))|=|(2+sqrt(3)-2+sqrt(3))/(1+(4-3))|` `=|(2sqrt(3))/2|=sqrt(3)="tan" pi/3 implies theta=pi/3=60^(@)` |
