I have a boat trying to cross a river with a current flowing ->

The boat is attempting to make it straight across (90d). In order to do this I have to change the volocity to 119.38 and the angle to 100.3.

So what is the speed of the current?

2. Relevant equations

3. The attempt at a solution

I tried solving using: cos(100.3) = -current/119.38

So -current = -21.345 but this is incorrect. Can anyone help?
