y^2 =5^2 −x^2   3x^2 +5x^2 =8×(3×5+5^2 −x^2 )  ⇒x^2 =20 ⇒x=2(√5)
$${y}^{\mathrm{2}} =\mathrm{5}^{\mathrm{2}} −{x}^{\mathrm{2}} \\ $$$$\mathrm{3}{x}^{\mathrm{2}} +\mathrm{5}{x}^{\mathrm{2}} =\mathrm{8}×\left(\mathrm{3}×\mathrm{5}+\mathrm{5}^{\mathrm{2}} −{x}^{\mathrm{2}} \right) \\ $$$$\Rightarrow{x}^{\mathrm{2}} =\mathrm{20}\:\Rightarrow{x}=\mathrm{2}\sqrt{\mathrm{5}} \\ $$

h^2 =x^2 −(((5+3)/2))^2 =x^2 −4^2   y^2 =5^2 −x^2   h^2 =y^2 −(5−4)^2 =5^2 −x^2 −1^2   5^2 −x^2 −1^2 =x^2 −4^2   x^2 =20 ⇒x=2(√5)
$${h}^{\mathrm{2}} ={x}^{\mathrm{2}} −\left(\frac{\mathrm{5}+\mathrm{3}}{\mathrm{2}}\right)^{\mathrm{2}} ={x}^{\mathrm{2}} −\mathrm{4}^{\mathrm{2}} \\ $$$${y}^{\mathrm{2}} =\mathrm{5}^{\mathrm{2}} −{x}^{\mathrm{2}} \\ $$$${h}^{\mathrm{2}} ={y}^{\mathrm{2}} −\left(\mathrm{5}−\mathrm{4}\right)^{\mathrm{2}} =\mathrm{5}^{\mathrm{2}} −{x}^{\mathrm{2}} −\mathrm{1}^{\mathrm{2}} \\ $$$$\mathrm{5}^{\mathrm{2}} −{x}^{\mathrm{2}} −\mathrm{1}^{\mathrm{2}} ={x}^{\mathrm{2}} −\mathrm{4}^{\mathrm{2}} \\ $$$${x}^{\mathrm{2}} =\mathrm{20}\:\Rightarrow{x}=\mathrm{2}\sqrt{\mathrm{5}} \\ $$

5−((5+3)/2)=5−4=1
$$\mathrm{5}−\frac{\mathrm{5}+\mathrm{3}}{\mathrm{2}}=\mathrm{5}−\mathrm{4}=\mathrm{1} \\ $$
