    45 will be special case where all angles be 45 Leme explain you a general case, with angle = x

    Hint: Except in geometrical solving of problems, NEVER EVER draw general diagrams with 45° angles. Always draw 20° to 30° angles. It will save you a lot of time.

    |dw:1359449644111:dw| WHere does this direction point to? If it is horizontal, then you are wrong again. "Your" angle is the other one.

    just remember when parallel to the slope means: Force produced by the weight-> mgsinx if its perpendicular ( normal ) to the slope, use mgcosx

    the original one, below the slope, angle use 45 degrees

    Ok. To anyone else answering, I will be leaving within 5 minutes. Thamks for all the help guys! At the very least, I know where the angles go, even if I do not knw how to derive it.

    you have to know your trigonometry well and have to look at different angles to solve this problem
