During a storm, a tree limb breaks off and comes to rest across a barbed wire fence at a point that is not in the middle between two fence posts. the limb exerts a downward force of 176 n on the wire. the left section of the wire makes an angle of 12.5° relative to the horizontal and sustains a tension of 413 n. find the (a) magnitude and (b) direction (as an angle relative to horizontal) of the tension that the right section of the wire sustains.
