Answer:   2-\frac{x}{\sqrt{x^{2}-25600}}

Hint: use basic concepts.

Solution:

We know,

\mathrm{y}=\mathrm{GA}+\mathrm{GB}+\mathrm{GC}

Then,

\begin{aligned} &y=2 x+120-\sqrt{x^{2}-160^{2}} \\ \end{aligned}

\frac{d y}{d x}=2-\frac{1}{2 \sqrt{x^{2}-160^{2}}} \\

\frac{d y}{d x}=2-\frac{x}{\sqrt{x^{2}-25600}}
