to form a triangle of forces, as long as the direction remains, the triangle can be formed referring to the direction.

How does he get 10.35N? When I type it in my calculator I get 107.1796->107.18 . Can someone help me with this one please.? BTW I am writing Engineering Science N1 tomorrow.

The only way I get 10.35N is to divide by 10.36 and round off to the second decimal. Where does the 10.36 come in play?
