The angle of elevation is about 16 degrees
Explanation:Given that the airplane rises vertically 1500 feet over a horizontal distance of 1 mile (5280 ft)
The angle of elevation is x, which is calculated as follows:
[tex]\begin{gathered} \tan x=\frac{1500}{5280}=\frac{25}{88} \\ \\ x=\tan^{-1}(\frac{25}{88})\approx16^o \end{gathered}[/tex]
