A train travels 3.5 kilometers on a straight track with a grade of 1 degree 10 minutes. What is the vertical rise of the train in that distance?

I'm pretty sure this is Triangle stuff, with Sin, Cos + Tan, etc.

I can't remember it all I'm afraid, but the angle will be the 1 degree, 10 minutes - the Hypotenuse side will be the 3.5 km
