Analytical Geometry (Parabola intersecting with a Line)
Posted:

Under what angle does a road that traces a line 3y2x+8=0 intersect a railway that traces y^2=8x parabola?
I think the angle asked here seems to be the one formed between the tangent line of the parabola and the given line (road) on their intersection points.
If so, what makes me confused is that there are two intersection points where two tangent lines are possible forming two different angles on those points.
Maybe I'm wrong and the solution is different.
Would you please help me?
Thanks and regards.
