I've got three questions from trig subject
1. How many inches will the weight in the figure rise if the pulley of 8.46 inches is rotated through an angle of 63deg53min.

2. Though what angle, to the nearest minute must the pulley in number 1 be rotated to raise the weight 15in?

3. The rotation of the smaller wheel in the figure causes the larger wheel to rotate. Through how many degrees will the larger wheel rotate if the smaller on rotates through 80deg?
