Given : the lines and

To find : angle between the lines

Formula used : If the lines are a + b + c + λ(p + q + r) and d + e + f +

λ(l + m + n) then the angle between the lines ‘θ’ is given by

θ =

the lines and

Here p = 3 , q = 2 , r = 6 and l = 1 , m = 2 , n = 2

θ = =

θ = = =

θ =

The angle between the lines and is
