1)A chandelier with mass m is attached to the ceiling of a large concert hall by two cables. Because the ceiling is covered with intricate architectural decorations (not indicated in the figure, which uses a humbler depiction), the workers who hung the chandelier couldn't attach the cables to the ceiling directly above the chandelier. Instead, they attached the cables to the ceiling near the walls. Cable 1 has tension T11 and makes an angle of 11 with the ceiling. Cable 2 has tension T22 and makes an angle of 22 with the ceiling.

Find an expression for T11, the tension in cable 1, that does not depend on T2. Express your answer in terms of some or all of the variables m, 11, and 22, as well as the magnitude of the acceleration due to gravity g. You must use parentheses around 11 and 2, when they are used as arguments to any trigonometric functions in your answer.
