Acandy necklace is extended from the top of a 10-foot ice cream cone to the ground. the necklace makes a 55 degree angle of the ice cream cone. how long is the necklace?

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

Now, from figure

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

d is correct
