Question

Hi, can you help to solve the exercise #13 please!!

Answer 1

`x=39\text{ degrees}`

Explanation:

This problem can be approached using trigonometric ratios, which are represented by:

Therefore, for an opposite side equals to 4 and adjacent equal to 5:

`\begin{gathered} \tan (x)=(4)/(5)_{} \\ x=\tan ^(-1)((4)/(5)) \\ x=38.6\text{ } \\ \text{Rounding:} \\ x=39\text{ degrees} \end{gathered}`
