In a "modern art" exhibit, a multicolored empty industrial wire spool is suspended from two light wires as shown in Fig. The spool has a mass of 50.0 kg, with an outer diameter of 75.0 cm and an inner axle diameter of 18.0 cm. One wire (#1) is attached tangentially to the axle and makes a 10° angle with the vertical. The other wire (#2) is attached tangentially to the outer edge and makes an unknown angle with the vertical. Determine the tension in each wire and the angle .
