I have having trouble solving this statics problem, I sum up the forces and have(adsbygoogle = window.adsbygoogle || []).push({});

C*cos(30) - B*cos(phi) = 0 in the positive x direction

and

C*sin(30) + B*sin(phi) - D =0 in the positive y direction

B = 275 lbs and D = 300lbs

I need to solve for C and phi, I have tried substitution, division, not matrices because it wouldn't work
