Homework Statement
Ok, so I'm in college now. However, I'm having the same problem i did when I was in high school. When your doing a problem that has let's say a truck on a 30 degree incline, how do you decide whether that angle will be touching the y component of the angle or the x? The reason I ask is because I was told the component touching the angle is always the x component, but in some problems that doesn't appear to be true, so I don't know how to draw my own force diagrams without mixing up the two.
