A mass of 10 kg is suspended from a ceiling by two cords that make angles of 30 and 45 degrees with the ceiling. Find the tension in each of the cords. This is how I set up my diagram. http://img205.imageshack.us/img205/1941/66920817mh7.th.jpg [Broken] I used the sine to try to find t1, but it doesn't work. I put the dotted line as 98N is that right?
