Solution:
\(\displaystyle\triangle{A}{B}{C}\)
\(\displaystyle{{\cos{{45}}}^{\circ}=}{\frac{{{9}}}{{{x}}}}\)
\(\displaystyle{x}={\frac{{{9}}}{{{\cos{{45}}}^{\circ}}}}\)
\(\displaystyle{x}={9}\sqrt{{2}}\)
\(\displaystyle{{\sin{{45}}}^{\circ}=}{\frac{{{y}}}{{{9}\sqrt{{2}}}}}\)
\(\displaystyle{y}={9}\sqrt{{2}}{{\sin{{45}}}^{\circ}\Rightarrow}{y}={9}\)
\(\displaystyle\triangle{A}{D}{C}\)
\(\displaystyle{{\sin{{45}}}^{\circ}=}{\frac{{{9}}}{{{z}}}}\)
\(\displaystyle{z}={9}\sqrt{{2}}\)
