    I drew a vector triangle with this information but I'm not sure if it matters. Would the answer be 2 (as this is the vector parallel to the slop in the triangle) or when worked out using the triangle, 2.74?

    Thanks!

    Unless I'm misreading the question, you have a component of weight acting down the slope, and a frictional force acting in the opposite direction so it's purely a 1D force problem. I can't see the need for any force triangle.
