3. The forces are weight and tension.
Working :-
T cos 45degrees + T cos 45degrees = 20N
2T cos 45degrees = 20N
T = 20N / (2 cos 45degrees)
= 14.14N
20 - 14.14 = 5.86N #

4. The forces are weight and tension.
Working :-
T1 sin 60degrees = 40N
T = 40N / (sin 60degrees)
= 46.19N #
T2 cos 80degrees = 40N
T = 40N / (cos 80degrees)
= 46.19 #

P.S. I just gave you the answer here. You have to do the triangle on your own.

6. The labeling do it by yourself.
Working :-
= mg cos thetha
= (2)(10) cos 30degrees
= 17.32N #
= mg sin thetha
= (2)(10) sin 30degrees
= 10N #

P.S. The "/ " is to signify division.
P.S.S. FYI, I'm a form 4 student too. I can understand your struggle.
