Given :  the lines   represented by 3x² + 2xy - y² = 0​

To Find : acute angle between the lines  

Solution:

3x² + 2xy - y² = 0​

=>  3x² + 3xy - xy - y² = 0​

=> 3x(x + y) - y(x + y) = 0

=> (3x - y)(x + y) = 0

=> 3x - y = 0  and x + y = 0

3x - y = 0

=> y = 3x

slope = 3

x + y = 0

=> y = -x

slope  = -1

α acute angles between lines

Tanα = | (3 - (-1) ) /( 1 + 3(-1)) |

=> Tanα = | 4) /(-2 ) |

=> Tanα = 2

=> α =   Tan⁻¹2

α =  63.435°
