Detailed Solution

The angle b/w the curves $y^{2} = 4 ax, x^{2} = 4 by$ at their intersection pt

$\tan θ = \frac{3 a^{1 / 3} b^{1 / 3}}{2 (a^{2 / 3} + b^{2 / 3})} y^{2} = 32 x, x^{2} = \frac{27}{2} y a = 8, b = \frac{27}{8} \tan θ = \frac{3 (2) (\frac{3}{2})}{2 (4 + \frac{9}{4})} = \frac{9}{(\frac{25}{2})} 5 \sqrt{\tan θ} = 3 \sqrt{2}$
