W = 28°

The question is asking..
"Which angle has a tan value of 0.5317?"

This can only be calculated using a calculator, tables or a very accurate graph. The process is called arc tan.

On a calculator it is usually shown as ${tan}^{- 1}$ $tan^-1$ not to be confused with $\frac{1}{tan}$ $1/("tan")$ which is the same as cot.

$tan^-1(0.5317) = 28°$
