is the force 11.780 N parallel to the plane ?

anonymous · Answer

what? im confused?

anonymous · Answer

mmm can you draw the 11780 N force in your diagram ? ?

anonymous · Answer

what does that mean?

anonymous · Answer

@nphuongsun93 can you help explain lol you know im slow.

anonymous · Answer

ooo i get it, sorry
in this case, you use cosine because you want to find the horizontal
cos 35 = x / 11780
x = 9649.61 N
