How do I solve for AD?

[marsh current]

you can start by finding CB, which is 30×cos(58) (this is used for finding DC later)
and then you can find AC, which is 30×sin(58)
then we need to find DC:
which is (30×cos(58))×tan(27)
then we subtract DC from AC to find AD
which leaves us with:
30×sin(58)-(30×cos(58))×tan(27) which is approximately:
17.34
