Solution:
Applying SOHCAHTOA,
Given the following dimensions below;
[tex]\begin{gathered} x=Opposite \\ Hypotenuse=22\text{ units} \\ \theta=43\degree \end{gathered}[/tex]Applying the sine formula
[tex]\sin\theta=\frac{Opposite}{Hypotenuse}[/tex]Substitute the values of the variables
[tex]\begin{gathered} \sin43\degree=\frac{x}{22} \\ x=22\times\sin43\degree \\ x=15.00396 \\ x=15.0\text{ units \lparen nearest tenth\rparen} \end{gathered}[/tex]Hence, the value of x is 15.0 units (nearest tenth)
