Can someone explain this to me

Answer:
[tex]\huge\boxed{\sf tan \ 28 = x / 14}[/tex]
Step-by-step explanation:
Since opposite and adjacent is given, we will use tan as trigonometric ratio.
Hence,
opposite = x , adjacent = 14 and [tex]\theta[/tex] = 28
So,
[tex]\sf tan \theta = opposite / adjacent[/tex]
tan 28 = x / 14
[tex]\rule[225]{225}{2}[/tex]
Hope this helped!
