1. Can someone please explain how to do this question??? Both parts please
Don't understand what it means nor how to even approach the question
2. R is resultant right so get the horizontal resultant Rx =(x + 15cos30) and Ry= 15sin30
50= (Ry/Rx)
But total resultant/magnitude= square root(Ry^2 + Rx^2)

What??
4. R is resultant right so get the horizontal resultant Rx =(x + 15cos30) and Ry= 15sin30
50=arc tan (Ry/Rx)
But total resultant/magnitude= square root(Ry^2 + Rx^2)

5. I personally think the easiest way to approach this question is to draw a vector triangle and then use the sine rule in order to work out R, and then do the same thing to work out X.

Split all the forces into vertical and horizontal components

Force Q is horizontal only so the vertical component of the resultant force (R) is equal to the vertical component of force P. Therefore Rsin50 = 15sin30 and you can solve that to get R = 9.79055N

Then,you need to do Rcos50 = Q - 15cos30
Since you know R already, just solve to get Q = 19.2832N

I attached my written solution as well
