"x-component :-3.73 ; y-component :+2.20"x-component :-3.73 ; y-component :+2.20
"Choice 2"Choice 2

Explanation:

A_x=+ A*cos(60^o)=+6*0.5=+3Ax=+A⋅cos(60o)=+6⋅0.5=+3
A_y=+A*sin(60^o)=+6*0.866=+5.196Ay=+A⋅sin(60o)=+6⋅0.866=+5.196

B_x=-B*cos(0^o)=-5*1=-5Bx=−B⋅cos(0o)=−5⋅1=−5
B_y=B*sin(0^o)=5*0=0By=B⋅sin(0o)=5⋅0=0

C_x=-C*cos(30^o)=-4*0.866=-3.464Cx=−C⋅cos(30o)=−4⋅0.866=−3.464
C_y=-C*sin(30^o)=-4*0.5=-2Cy=−C⋅sin(30o)=−4⋅0.5=−2

D_x=+D*cos(30^o)=+2*0.866=+1.732Dx=+D⋅cos(30o)=+2⋅0.866=+1.732
D_y=-D*sin(30^o)=-2*0.5=-1Dy=−D⋅sin(30o)=−2⋅0.5=−1

Sigma x=A_x+B_x+C_x+D_x
Sigma x=+3-5-3.464+1.732
color(red)(Sigma x=-3.73)

Sigma y=A_y+B_y+C_y+D_y
Sigma y=5.196+0-2-1
color(green)(Sigma y=+2.20)
