a spring is attached at one end to support b and at the other end to collar a, as represented in the figure. collar a slides along the vertical bar between points c and d. in the figure, the angle is the angle created as the collar moves between points c and d. Part A when 0 = 28 degrees, what is the distance from point A to point B to the nearest tenth of a foot?
Part B When the spring is stretched and the distanced from point A to point B is 5.2 feet, what is the valuue of 0 to the nearest tenth of a degree?
