Velocity problem set up (I think it is velocity)

[MarieWynn]

Homework Statement

A boat capable of making 12.0 km/h in still water is used to cross a river flowing at speed of 2.0 km/h. The boat is directed (from the perpendicular to the shore) in such a way that its resulting motion is straight across the river.
At what angle (in degrees) must the boat be directed?
What is the resultant speed relative to the shore?

Homework Equations

That's the problem I am having. I have no clue how to set up this problem (I'm extremely new to physics).

The Attempt at a Solution

Again, no attempt yet because I am stuck on set up. Which is really all I need help with--just figuring out how to set it up, not the math. Thanks :)

In order for the boat to make it straight across the river, it's going to have to aim for a point upstream, since the current is going to push downstream, right? (Think vector math)
