Slope of two lines are `(-(5)/(6))` and`(1)/(11)` resp.then angle between two lines is.............

Find the angles between two lines.

Distance and Angle between Two Lines

The slopes of two lines are (1)/(2) and 3 . Find the angle between them.

Angles between two lines alpha-beta

The directions rations of two lines are 3,2,-6 and , 1,2,2 respectively . The acute angle between these lines is

The direction rations of two lines are a,b,c and (b-c) , (c-a),(a-b) respectively . The angle between these lines is

If the direction ratios of two lines are (1,2,4) and (-1,-2,-3) then the acute angle between them is

If direction-cosines of two lines are proportional to 4,3,2 and 1, -2, 1, then the angle between the lines is :

If direction ratios of two lines are 5,-12,13 and -3,4,5 , then the angle between them is

Direction ratios of two lines satisfy the relations 2a-b+2c=0 and ab+bc+ca=0 . Then the angle between two lines is
