1. The problem statement, all variables and given/known data 32. Three gears are arranged as shown in the figure below. Find the angle [tex]\phi[/tex] 46. Prove that the area of a parallelogram is the product of two adjacent sides and the sine of the included angle. 2. Relevant equations 3. The attempt at a solution 32. I assumed that since the gears touch that I could add their radius. Would that be incorrect? I was thinking I had to use the linear and angular speed formulas, but I wasn't sure. I know that their linear speed is equal, but I don't think I need to do all that. 46. I followed the steps in which they obtained the Area of a triangle.
