Check the picture below.


\textit{using the pythagorean theorem} \\\\ c^2=a^2+b^2\implies c=√(a^2 + b^2) \qquad \begin{cases} c=hypotenuse\\ a=\stackrel{adjacent}{9}\\ b=\stackrel{opposite}{11}\\ \end{cases} \\\\\\ c=√(9^2 + 11^2)\implies c=√(202)\implies {\Large \begin{array}{llll} c\approx 14.2 \end{array}}
