Answer:
The length of the necklace is 12.20 foot
Step-by-step explanation:
Given as :
The height of the ice cream cone to the ground = h = 10 foot
The angle make by the necklace of the ice cream cone = 55°
Let The length of the necklace = L foot
<u>Now, from figure </u>
Height = BC = h foot
The length of the necklace = L = AC
So, Sin angle = 
Or, Sin 55° = 
Or, 0.8191 = 
Or, 0.8191 = 
Or, L = 
∴ L = 12.20 foot
So, The length of necklace = L = 12.20 foot
Hence The length of the necklace is 12.20 foot Answer
