Physics help problem-component force and finding X distance?

[physicsman1234]

Homework Statement

have set up my diagram but I am unsure how to approach each problem.

For this first picture http://tinypic.com/r/25i9gkh/5

I just need to find By and Bx

for the second picture http://tinypic.com/r/25i9gkh/5

I need to find the distance of x.

Thanks to anyone who is willing to help.

Homework Equations

Not sure...

The Attempt at a Solution

Ax = Bx

By + Ay = 850N + 882.63N

B y (20m) = 850N(5m) + 882.63N(10m)

Here is my diagram of the first question http://tinypic.com/r/25i9gkh/5
----------------------------------------------------------------------------------------------
For the second question I know: 2B = 420 + 640 + 180

Here is the picture, I have to find X

All of your pictures are the same. (And they have the same URL) It is not clear what distance 'x' you are trying to find.

If you are trying to put this system into static equilibrium, then write an equation for the sum of the forces and an equation for the moments about a convenient point. For this case, I would suggest you use the right end where B is located.
