please help me on this question!

Answer:
[tex]x=17.798[/tex]
Step-by-step explanation:
From the diagram given, [tex]x[/tex] is the opposite side of the angle. With this information, we can write:
[tex]sin(54^{\circ})=\frac{x}{22}[/tex] (SOHCAHTOA)
[tex]\frac{x}{22}[/tex] = [tex]0.809[/tex] (to the nearest hundredth)
[tex]x=0.809\times22[/tex]
[tex]=17.798[/tex]
∴ [tex]x=17.798[/tex]
Hope this helps :)
