    In respect to angle 35 where is x and side 18? Opposite, adjacent or hypotenuse?

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