The question is to determine the magnitude, direction and sense of the resultant force of the nonconcurrent force system. Locate the resultant with respect to point O.(adsbygoogle = window.adsbygoogle || []).push({});

I've looked at example in the book and tried to follow this problem as close to it as possible.

(1)I first tried to find the x and y components of the forces. Since I'm finding the x component, it will be cosine. I set it up as 15cos75-25(12/13) but am not sure if that's correct. Also Correct me if I'm wrong with my signs. I then found the y value, but I'm still not sure if I have set it up correctly or have any of the signs right for the the 10, 15 and 25. Correct me if I'm wrong.

(2) I then used a^2+b^2=c^2. I did -5.73^2+15.75^2=square root of 280.89=16.76

(3) I don't know what its called but its a symbol of an 'x' with a line above it equals the inverse tangent of the y and x component. So i took the inverse tangent of the y component over the x component. As you can see i did the inverse tangent of 15.75/-5.73=-70.71.

(4)The example in the book did not use either of the 4 numbers pictured(8',6',5',4'). So I assumed that it was not used in this problem.
