((AF)/(AD))=((AB)/(AH))=((3k)/(3k+(√2)k+(√2)k))=(3/(3+2(√2)))  ((ED)/(AD))=((BC)/(AC))=(((√2)k)/(3k+(√2)k))=((√2)/(3+(√2)))  (x/y)=((AF)/(ED))=(3/(3+2(√2)))×((3+(√2))/( (√2)))=((15)/( (√2)))−9≈1.6066
$$\frac{{AF}}{{AD}}=\frac{{AB}}{{AH}}=\frac{\mathrm{3}{k}}{\mathrm{3}{k}+\sqrt{\mathrm{2}}{k}+\sqrt{\mathrm{2}}{k}}=\frac{\mathrm{3}}{\mathrm{3}+\mathrm{2}\sqrt{\mathrm{2}}} \\ $$$$\frac{{ED}}{{AD}}=\frac{{BC}}{{AC}}=\frac{\sqrt{\mathrm{2}}{k}}{\mathrm{3}{k}+\sqrt{\mathrm{2}}{k}}=\frac{\sqrt{\mathrm{2}}}{\mathrm{3}+\sqrt{\mathrm{2}}} \\ $$$$\frac{{x}}{{y}}=\frac{{AF}}{{ED}}=\frac{\mathrm{3}}{\mathrm{3}+\mathrm{2}\sqrt{\mathrm{2}}}×\frac{\mathrm{3}+\sqrt{\mathrm{2}}}{\:\sqrt{\mathrm{2}}}=\frac{\mathrm{15}}{\:\sqrt{\mathrm{2}}}−\mathrm{9}\approx\mathrm{1}.\mathrm{6066} \\ $$
