Help me in these equation please![tex] {6}^{2} + {10}^{2} = {c}^{2} [/tex]

Determine the length of side c, by using the pythagoras theorem.
[tex]\begin{gathered} c^2=a^2+b^2 \\ c^2=(10)^2+(6)^2 \\ c=\sqrt[]{100+36} \\ =\sqrt[]{136} \\ =11.661 \\ \approx11.66 \end{gathered}[/tex]So answer is c = 11.66.
