SOLUTION:

Case: Trigonometry

Method:

The trigonometry functions for the triangle below are:

Hence:


\begin{gathered} sin40\degree=(Opp)/(Hyp) \\ sin40\degree=(x)/(z) \end{gathered}

And


\begin{gathered} cos40\degree=(Adj)/(Hyp) \\ cos40\degree=(y)/(z) \end{gathered}

And


\begin{gathered} tan40\degree=(Opp)/(Adj) \\ tan40\degree=(x)/(y) \end{gathered}

Final answer: Option (C)


tan40\degree=(x)/(y)
