Two forces are applied to a car in an effort to accelerate it. one is 450N and is applied noth of west at a 10 degree angle and the other is 380N, applied north of east at a 30 degree angle. What is the resultant of these two forces?
I attatched a file to provide a visual aid even though it's not a very good. I'm confused by the question it self. A resultant is a vector representing the sum of two or more vectors. For the problems I've been doing, that usually the hypotenuse of a right triangle. If you draw an imaginary line down and then right or left depending on which vector, it makes a right triangle. It appears to me that they are already resultants.

With vectors, you can move them around (as you are supposed to) to add them. Move one of the vectors so that its tail (butt) is in the other vectors head (arrow), and then draw your hypotenuse like that.
