  • The horizontal component of vector A is drawn in blue.

A_x= A .cos theta

-20=A. cos (130)

cos(130)=-cos (50)=-0.64278761

-20=A .(-0.64278761)

A=(-20)/(-0.64278761)

A=31.11" units"

  • The vector A is drawn in red.

  • The vertical component of vector A is drawn in green.

enter image source here

cos(40)=sin(50)=0.76604444

A_y=A. cos(40)=31.11*0.76604444

A_y=31.11*0.76604444

A_y=23.83" units"
