Math Problem Statement
Ropes 3 m and 5 m in length are fastened to a holiday decoration that is suspended over a town square. The decoration has a mass of 9 kg. The ropes, fastened at different heights, make angles of 52° and 40° with the horizontal. Find the tension in each wire and the magnitude of each tension (in N). (Use g = 9.8 m/s2 for the acceleration due to gravity. Round your answers to two decimal places.)
