I’m not too sure how to solve this question, can you please help me break this down?

Answer:
The image of the question is broken down below as
From the image above, we will have the following values given
[tex]\begin{gathered} opposite=3 \\ adjacent=4 \\ hyptenus=5 \end{gathered}[/tex]To figure out the value for Cos (A), we will use the trigonometric ratio below
[tex]\cos(A)=\frac{adjacent}{hypotenus}[/tex]By substituting the values in the formula above, we will have
[tex]\begin{gathered} \cos(A)=\frac{adjacent}{hypotenus} \\ \cos(A)=\frac{4}{5} \end{gathered}[/tex]Hence,
The final answer is
[tex]\Rightarrow\cos(A)=\frac{4}{5}[/tex]
