m3 m2 mi Three strings are tied together. They lie on top of a circular table and the knot is exactly in the center of the table, as shown in the figure (top view). Each of the strings hangs over the edge of the table, and a weight is supported from it. The masses m = 3.89 kg and m2 = 5.79 kg are known. The angle a = 76.0 degrees between strings 1 and 2 is also known. What is the angle between strings 1 and 3? (Please specify your answer in degrees.)
