A 400 kg piano is being lowered into position by a crane while two people steady it by ropes pulling to the sides. Bob's rope pulls to the left, 15 degree below horizontal, by 380 N of tension. Ellen's rope pulls toward the right, 25 degree below horizontal.

1. What tension should Ellen maintain in her rope to keep the piano descending at a steady speed?

2. What is the tension in the vertical main cable supporting the piano?
