\qquad \tt \rightarrow \:Angle \:\: of \:\: elevation= 30°

____________________________________

\large \tt Solution  \: :

Let the angle of elevation be " x "

\qquad \tt \rightarrow \:  \cos(x)  =  \dfrac{9 \sqrt{3} }{18}

\qquad \tt \rightarrow \:  \cos(x)  =  \dfrac{ \sqrt{3} }{2}

\qquad \tt \rightarrow \: x =  \cos {}^{ - 1}  \bigg( \cfrac{ \sqrt{3} }{2} \bigg )

\qquad \tt \rightarrow \: x = 30 \degree \:  \:  or \:  \:  \cfrac{ \pi}{6}   \:  \: rad
