Find the angle between the lines 
and 
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
