Determine the resultant forces acting on objects subject to the following forces acting at a point on the object:

(a) A force of 3 N acting horizontally and a force of 4 N acting at the same point on the object at an angle of 60° to the horizontal.

(b) A force of 3 N in a westerly direction and a force of 6 N in a northerly direction.

(c) Forces of 4 N and 5 N with an angle of 65° between them.

(d) Forces of 3 N and 8 N with an angle of 50° between them.

(e) Forces of 5 N and 7 N with an angle of 30° between them.

(f) Forces of 9 N and 10 N with an angle of 40° between them.

(g) Forces of 10 N and 12 N with an angle of 105° between them.
