If `m` is the slope of a line and `m + 2 = m + 3`.then the possible angle between line and x-axis is

If slope of a line is “1” then the angle between the line and X -axis is

If m_(1) , m_(2) are the slopes of two lines and theta is the angle between two lines then tan theta =

If m_(1),m_(2) are the slopes of two lines and theta is the angle between two lines then tan theta =

If 'm_(1)',m_(2)' are the slopes of two lines and theta is the angle between two lines then tan theta=

If the slope of one of the lines 2x^(2) + 3xy + lambda y^(2) = 0 is 2 then the angle between the lines is

If the angle between two lines is 45^(@) and the slope of one line is 2, then the product of possible slopes of other line is

If the angle between two lines is 45^(@) and the slope of one line is 2, then the product of possible slopes of other line is

If m = 1 is the slope of a line L, then the product of the slopes of non-parallel lines which are inclined at an angle of 60^(@) with L is

The straight line L-=X+Y+1=0 and L_1-=X+2Y+3=0 " are intersectiong, m is the slope of the straight line " L_2 " such that L is the bisector of the angle between " L_1 and L_2 " The value of " m^2 is .

Derive a formula for the angle between two lines with slope m1 and m2.Hence find the acute angle between the lines sqrt 3x+y=1 and x+sqrt3 y=1 .
