Right now I'm currently stuck with the vector highlighted in red. I just don't understand if it the angle that it is in or the length that is wrong.

The diagram appears to have two forces that are labeled "mg" (one red and the other blue). What type of force does "mg" represent? How many such forces act on the car?

I added an extra vector. I was mistakenly adding the mg sin and mg cos
