Question

Ronel and Aini are pulling two rope that are tied to Wilfred. The angle between two ropesis 120 degree. Ronel pulls with a force of 150 Non bearing of 330 degree. Aini applies a force of 120 N on bearing of 090 degree. Use a scale of 1cm:20 N to find force applied to Wilfred.​

While many people would like to simply add the forces from each end to get a total force, this is fundamentally incorrect.

This is an application of Newton's Third Law: "For every action there is an equal and opposite reaction." The only way someone on one end of the string can exert a force of 10 N on the other end of the string is of the other end of the string exerts a 10 N force in the opposite direction.

Suppose I hang a 1 kg mass from a spring scale. This pulls with a force of approximately 10 N. Next, remove the weight and attach the spring scale to a wall. Pull on the scale until it reads 1 kg. That's the same 10 N force that the weight (and gravity) exerted downward when it was hanging. Lastly, consider what would happen if you attached a second spring scale to the wall and the end of the string to that spring scale. When you pull one hard enough to make it read 1 kg, the spring scale on the opposite end will also show 1 kg. They are indicating equal forces in opposite directions.
