α =(360⁰ - 2•100⁰)/2=80⁰

F12=sqrt{F1²+F2²-2•F1•F2•cosα}=

=sqrt{400+400-2•20•20•cos80⁰}=25.71 N

Direction:

F1 is directed along the positive X-axis ,and F2 is 100⁰ measured from

the positive X- axis with the counter-clockwise, F is 230⁰measured from

the positive X- axis with the counter-clockwise
