Given : h = 16m , Angle = 18 degrees, firnd : lenght of the rope
This problem is an application of trigonometric function.
Solution : Using trigonometric function
sin 18 = h / L, where h is the height and L is the lenght of the rope.
0.3090 = 16/L
0.3090 L = 16 dividing both sides by 0.3090
L = 51.77 meters. answer
