Homework Statement
Three horizontal ropes are attached to a boulder and produce the pulls shown in the figure.
1) Find x and y components of pulls A,B,and C
2) Find the components of the resultant of the 3 pulls
3) Find the magnitude of the resultant pull
4) Find direction of the resultant pull
Homework Equations
The Attempt at a Solution
I was able to find x/y components of pull A, but I'm not sure how to do it for B and C. I tried using 80cos30 and 80sin30 for pull B but it did not work. Can somebody tell me what I may be doing wrong? And could someone explain how to approach part 2? Thanks!
