Physics help?! / acceleration?

Y'all are probably going to hate me because I'm adding like 3 questions that I just don't understand.

1. A 12kg box is accelerating down a ramp with an incline of 48°. N= 78.69 Mk= .51
What is the acceleration of the box down the ramp?

2. A 56N force is applied down and to the right at an angle of 28° to a 35kg box. There is no friction. N= 369.3
What is the horizontal acceleration of the box?

3. A box is dragged across the floor by a force at an angle.
F= 100N. M= 10kg. friction= 25N. Angle= 36.9
What is the acceleration of the box?
