Given data:
The sun 55 foot tall.
Shadow = 16 foot long
Now, by using the trigonometric ratio finding the angle of elevation
[tex]\tan \theta=\frac{perpendicular}{base}[/tex][tex]\begin{gathered} \tan \theta=\frac{55}{16} \\ \tan \theta=3.4375 \\ \theta=73^{\circ}47^{\prime} \end{gathered}[/tex]
Thus, the angle of elevation is 73.8 and the correct option is (A)
