Hi I have a homework problem I can't understand: A 125-N sign is supported by a lightweight pole and cable as shown in the diagram. What is the tension in the cable? the diagram resembles |> the | is a wall, the top of > is the cable and the bottom is the pole, and the sign hangs from point at the right. The pole makes a 40 degree with the wall, and the cable is 50 degrees, so where the pole and cable meet is a right angle. can anyone give a hint on how to solve that?
