The equations of the symmetric lines of two inner angles of triangle ABC are given:

x+4=0 and 4x+7y+5=0, and the equation of the line of one of the sides of the triangle is

given 3x+4y=0 (which goes through the points of the side where the symmetric lines are

going). Find the equations of the lines which are going among the other two sides of the

triangle.

2. Relevant equations

[tex]d=\frac{|Ax + By + C|}{|\sqrt{A^2+B^2}|}[/tex]

3. The attempt at a solution

I found one of the dots A(-4,3). Also I find that the lines are going through the point (0,0)
