To solve the problem, we need to find the angle subtended by the chord of contact at the vertex of the parabola \(y^2 = 4ax\) when tangents are drawn from any point on the line \(x + 4a = 0\). ### Step-by-step Solution: 1. **Identify the Parabola and the Line**: - The equation of the parabola is \(y^2 = 4ax\). - The line from which tangents are drawn is given by \(x + 4a = 0\) or \(x = -4a\). ...
