Find X,Right triangle with X being the adjacent,33 being the opposite and 49 being the degree.

$$tan49^0=\frac{33}{x}$$

When x is on the bottom I usually just turn everything upside down (note x cannot =0)

$$\frac{1}{tan49^0}=\frac{x}{33}\\\\
\frac{33}{tan49^0}=x$$

etc

you would have to find the tangent of 49. so 33/X.
