Review “Stuff” Elena got ANOTHER new bike! Solve the following Triangle: α= 42°, a = 6, b = 7 • These bike wheels are 1 yard in diameter, with the pedal sprocket ¾ ft in diameter and the wheel sprocket 6 inches in diameter. The wheel sprocket is spinning at 300 RPM. Find the angular speed of the wheel and both sprockets.
