I was not aware of that. So if the item is in equilibrium, this causes the angles from the two strings to be equal to each other? With this info I can solve it. I'll be posting soon.
I approached this question with a free body diagram.
my Verticle length of BA is y-2
AC= 15-AB
Horizontal length of AC= a; Horizontal length of BA=10-a
I have too many unknowns in this problem and I don't know any directions(angle).
I know that I should start at the weight and try to resolve the...
