You are not analyzing this problem correctly. You want to find the components of the 660 N force in lines AC and BC such that static equilibrium is maintained.

The sum of the horizontal components in lines AC and BC must be equal and opposite of the 660 N force directed to the right of the page, while the sum of the vertical components in lines AC and BC must equal zero. Write the equations of statics and solve them.
