Physics displacement/horizontal and vertical componenets help!?

I have this 30 problem packet for Physics that I'm TOTALLY lost on.

Could you please do these three problems step by step so I can do the packet?

1. Ivan pulls a sled loaded with logs to his cabin in the woods. If Ivan pulls with a force of 800.N in a derection 20.0 above the horizontal, what are the horizontal and vertical components of the force exerted by Ivan?

2. Marcie shovels snow after a storm by exerting a force of 30.0N on her shovel at an angle of 60.0* to the vertical. WHat are the horizontal and vertical componenets of the force exerted by Marcie?

3.Amit flies due east from San Francisco to Washington DC, a displacement of 5600. km. He then flies from Washington to Boston, a displacement of 900. km north. What is Amit's total displacement?

Thanks!

    1,- x=800cos20=751.7N

    y=800sin20=273.6N

    2.-60* off the vertical means 90-60=30* above the horizontal

    x=30cos30=25.98N

    y=30sin30=15N

    3,-total displacement = redical(5600^2+900^2)=5671.86km

    note:

    y=vertical

    x-horizontal
