a candy 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

Finger [1]

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

Now, from figure

Height = BC = h foot

The length of the necklace = L = AC

So, Sin angle = $\dfrac{\textrm perpendicular}{\textrm hypotenuse}$

Or, Sin 55° = $\dfrac{\textrm BC}{\textrm AC}$

Or, 0.8191 = $\dfrac{h}{L}$

Or, 0.8191 = $\dfrac{10 foot}{L}$

Or, L = $\dfrac{10 foot}{0.8191}$

∴ L = 12.20 foot

So, The length of necklace = L = 12.20 foot

Hence The length of the necklace is 12.20 foot Answer

Is −8>6 true or false

Helen [10]

False. Negative numbers aren’t greater than positive numbers. For it to be true it would have to be -8<6.

Answer:

Total Area = Area of Triangle + Area of Semicircle

Total Area = 1/2(bh) + 1/2(pir^2)

Total Area = 1/2(120) + 1/2(3.14(36))

Total Area = 60 + 18(3.14)

Total Area = 116.52
