Question

Kyle is pulled back on a swing so that the rope forms an angle of 30 degrees with the vertical. The distance from the top of the swing set directly to the ground is 12 feet. What will Kyle's height off the ground,( )x, when he is in the pulled back position. . A. 3.34 feet B. 3.86 feet. C. 8.56 feet. D. 8.66 feet

Answer 1

Length of rope = 12 - 2 = 10ft
Vertical length of Kyle from the top of the rope when pulled to position is 10cos30° = 8.66 ft

Kyle's height of the ground = 12 - 8.66 = 3.34 ft
