Answer
The wingspan $C{C}'$ is $41\text{ feet}$.
Work Step by Step
At first we will reconstitute the graph as below:
By observing the figure, we will find angle A:
$\begin{align}
& A=180{}^\circ -150{}^\circ \\
& =30{}^\circ
\end{align}$
Now, we will find d by using the law of sines:
$\begin{align}
& \frac{d}{\sin A}=\frac{36}{\sin 90{}^\circ } \\
& \frac{d}{\sin 30{}^\circ }=\frac{36}{\sin 90{}^\circ } \\
& d=\frac{36\sin 30{}^\circ }{\sin 90{}^\circ } \\
& d=18
\end{align}$
Therefore, the wingspan $C{C}'$ is $18+5+18=41\text{ feet}$.
