unknown To calculate the unkonown angle, we will use the trigonometric ratio below
[tex]\tan \theta=\frac{opposite}{\text{adjacent}}[/tex]
where,
[tex]\begin{gathered} \text{opposite}=76 \\ \text{adjacent}=57 \end{gathered}[/tex]
By substituting the values, we will have
[tex]\begin{gathered} \tan \theta=\frac{76}{57} \\ \tan \theta=1.3333 \\ \theta=\tan ^{-1}1.333 \\ \theta=53.13^0 \\ \text{Appro}\xi\text{mately} \\ \theta=53^0 \end{gathered}[/tex]
Hence,
The final answer is = 53°
