OMGGGG I DONT GETTT IT.

brain has shutdown.

6cos60 is the same as 6sin30

elemis:
The 6 N force makes an angle of 60 degrees with the y axis. I used this 60 degrees when resolving in the Y DIRECTION.

Dania:
Asif :)

I keep getting a tension of 8.32N when in fact I need to get 3N. I think I'm resolving the forces incorrectly, can someone please draw it out for me, and solve the question.
