17.36 degrees
Explanation
Step 1
Diagram:
so, we have a rigth triangle then let
[tex]\begin{gathered} angle\text{ =}\theta \\ opposite\text{ side= 2.47} \\ adjacent\text{ side =7.9} \end{gathered}[/tex]Step 2
now, we need a function that relates those values to find the missin angle , it is
[tex]tan\theta=\frac{opposite\text{ side}}{adjacent\text{ side}}[/tex]replace ans solve for the angle
[tex]\begin{gathered} tan\theta=\frac{2.47}{7.9} \\ tan\theta=0.31 \\ inverse\text{ tan function in both sides} \\ \tan^{-1}(tan\theta)=\tan^{-1}(0.31) \\ \theta=17.36\text{ \degree} \end{gathered}[/tex]therefore, the answer is
17.36 degrees
I hope this helps you
