1. The problem statement, all variables and given/known data I need to find the component of W (the 400N force) that is parallel to the slide as in the attached picture. As you can see there is a 24 degree angle between the surface and ground. 2. Relevant equations 3. The attempt at a solution I should be using simple trigonometry. The equation I am looking for is 400cos66 (or the appropriate version of sin) to give me an answer of 163N. So any help on how to find the triangle that would help me solve this problem would be appreciated.
