How to solve this six equations f1,f2,f3,f4,f5,f6 for finding out unknown x(1),x(2),​x(3),x(4),​x(5),x(6) using fsolve,solve.

f1=1-2*cos(x(1)*pi/180)+2*cos(x(2)*pi/180)-2*cos(x(3)*pi/180)+2*cos(x(4)*pi/180)-2*cos(x(5)*pi/180)+2*cos(x(6)*pi/180)-(pi/4)*(.1);

f2=1-2*cos(5*x(1)*pi/180)+2*cos(5*x(2)*pi/180)-2*cos(5*x(3)*pi/180)+2*cos(5*x(4)*pi/180)-2*cos(5*x(5)*pi/180)+2*cos(5*x(6)*pi/180);

f3=1-2*cos(7*x(1)*pi/180)+2*cos(7*x(2)*pi/180)-2*cos(7*x(3)*pi/180)+2*cos(7*x(4)*pi/180)-2*cos(7*x(5)*pi/180)+2*cos(7*x(6)*pi/180);

f4=1-2*cos(11*x(1)*pi/180)+2*cos(11*x(2)*pi/180)-2*cos(11*x(3)*pi/180)+2*cos(11*x(4)*pi/180)-2*cos(11*x(5)*pi/180)+2*cos(11*x(6)*pi/180);

f5=1-2*cos(13*x(1)*pi/180)+2*cos(13*x(2)*pi/180)-2*cos(13*x(3)*pi/180)+2*cos(13*x(4)*pi/180)-2*cos(13*x(5)*pi/180)+2*cos(13*x(6)*pi/180);

f6=1-2*cos(17*x(1)*pi/180)+2*cos(17*x(2)*pi/180)-2*cos(17*x(3)*pi/180)+2*cos(17*x(4)*pi/180)-2*cos(17*x(5)*pi/180)+2*cos(17*x(6)*pi/180);
