Answer:
...
Step-by-step explanation:
since they give us the side opposite of the given angle(Opposite) and we are trying to find for a (Adjacent/side), so we use TOA
tan(30)= [tex]\frac{4}{a}[/tex]
i see u dont want it solved but ill solve it anyways
since a is on the bottom then lets switch them
[tex]x=\frac{4}{tan30}[/tex]
x= 6.928
