Draw a picture and the answer should be fairly simple:dw:1359421352236:dw\[A=16^{\circ}\]\[Ax=Acos(\theta)\]\[Ay=Asin(\theta)\]

but i don't kno what to do.. Do i subtract 360344?

Yes, to find the angle above (as I did) you do 360344. That gives you theta

So to find the amount of force in just the x direction you would have:\[F_x=(384N)cos(16)=369.12N\]

Question 2 of 6 F points in the opposite direction as F and has the same magnitude as F True/False Question 3 of 6 F1 = (8.4,3.4) and F2 = (7.1,5.8) where all components are in newtons. What is the exact xcomponent of F1 + F2 (in newtons)?

The first one is true. For the second one you have to do vector addition: F1=(8.4,3.4) which states that the x value is 8.4 and the y value is 3.4. F2=(7.1,5.8) which states that the x value is 7.1 and the y value is 5.8. The resultant vector (in component notation) will simply be: Fresult=[(8.4+(7.1)), (3.4+(5.8))]Just perform the math and you'll know what the answer to the second question is.

dont i just need the value of x? so it will be 8.4+7.1 = 1.3

If it's not clear, I'm just adding the x's and y's. You should end up with Fresult=(1.3, 2.4)

ok thanks!. how would u do this question. F = (30.8,44.4), where all components are in newtons. If a vector's direction is measured counterclockwise from the positive xaxis, what angle (in degrees, from 0360) does the negative vector F make?
