The slope of tangents drawn from a point (4,10) to the parabola y^(2)=9x are

Find the angle between tangents drawn from P(2, 3) to the parabola y^(2) = 4x

Find the angle between tangents drawn from P(2, 3) to the parabola y^(2) = 4x

If two tangents drawn from (a ,b) to the parabola y^(2)=4x are such that slope of one of the tangent is double the other then (9a)/(b^(2)) is
