I cannot figure this question out, please help. 5 stars to best answer.

Q: A boat that can travel 2.5 m/s on still water is now on a river that flows due East at a velocity of 2.0 m/s. What is the velocity of this point with reference to a point on the shore when the bot is headed 45.0° W of N (135°)?

Thanks. Please show work

I think the answer is 1.8m/s 6.30° E of N or something around that. Problem is I have no clue how to get that answer and I've spent hours on it, I swear.

That's the right answer but I'm supposed to figure out how to get there. After using a bunch of numbers I found that 2.5cos45 gets the right speed and tan-1(0.5/4.5) gets the right angle, but I don't understand how to get to that point.
