sin=SOH
cos=CAH
tan=TOA
where
O=opposite
A= Adjacent
H=Hypotenuse
In respect to angle 35 side 18 and x are opposite and the hypotenuse
O and H ok?
Tell me which one uses both O and H?

Yes
\[\sin(35^o)=\frac{opposite}{hypotenuse}\]\[\sin(35^o)=\frac{18}{x}\]\[{x*}\sin(35^o)=18\] \[x=\frac{18}{\sin (35^o)}\]
