Answer :

Given:


The equations of the lines are


(m2 mn) y = (mn + n2) x + n3 … (1)


(mn + m2) y = (mn n2) x + m3 … (2)


To find:


Angles between two lines.


Explanation:


Let m1 and m2 be the slopes of these lines.



Let θ be the angle between the lines.


Then,






Then,




Hence, the acute angle between the lines is
