$x^2+( 5\sqrt2-x)^2= (5\sqrt2)^2\\
x^2+50-10\sqrt2x+x^2=50\\
2x^2-10\sqrt2x=0\\
x^2-5\sqrt2x=0\\
x(x-5\sqrt2)=0\\
x=0 \vee x=5\sqrt2$

Server to cook ratio is 5 : 2added = 7
this means that 5/7 of the cooks and servers are servers and 2/7 of the cooks and servers are cooks

so if the total cooks and servers is 42..
5/7 * 42 = 210/7 = 30 of them are servers <===
2/7 * 42 = 84/7 = 12 of them are cooks
