Question

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

Answer 1

The image of the question is broken down below as

From the image above, we will have the following values given

`\begin{gathered} opposite=3 \\ adjacent=4 \\ hyptenus=5 \end{gathered}`

To figure out the value for Cos (A), we will use the trigonometric ratio below

`\cos(A)=(adjacent)/(hypotenus)`

By substituting the values in the formula above, we will have

`\begin{gathered} \cos(A)=(adjacent)/(hypotenus) \\ \cos(A)=(4)/(5) \end{gathered}`

Hence,

The final answer is

`\Rightarrow\cos(A)=(4)/(5)`
