|dw:1430215645216:dw| the thing sis not moving so there is no net force on it. the forcesare the tensions in the cables and its weight, and these cancel out in the horizontal direction and vertical y direction. thus you should create equations in the x and y directions. you have the angles that are needed to do this.
