Length of the hypotenuse of the triangle to the nearest tenth of a metre
Lemur [1.5K]

Answer:

The length of the hypotenuse is 2.4m

Step-by-step explanation:

well to start we have to know the relationship between angles, legs and the hypotenuse

α = 55°

o: opposite  = 2.0m

h: hypotenuse

sin α = o/h

cos α= a/h

tan α = o/a

we see that it has (angle, hypotenuse, opposite)

we look at which meets those data between the sine, cosine and tangent

is the sine

sin α = o/ah

Now we replace the values ​​and solve

sin 55 = 2.0/h

0.81915 = 2.0/h

h = 2.0 / 0.81915

h = 2.4415 m

round to the nearest tenth

h = 2.4415 = 2.4 m

The length of the hypotenuse is 2.4m

Aaron used links to create a chain 28.9 cm long.Each link is 1.7 cm long.How many links are in the chain?
dusya [7]
You are given the length of the chain equal to 28.9cm. For each link, the length is 1.7cm long. You are required to find how many links are there in the chain. You just divide 28.9 cm by 1.7 cm to get the answer. The solution is,  
<span>
Number of links = chain length/link  length</span>
Number of links = (28.9cm)/(1.7cm)
<span>Number of links = chain length/link  length</span>
Number of links = 17  
<span><u><span>There are 17 links in a 28.9cm chain length.</span></u><u /></span>

jok3333 [9.3K]
We Know, Area = Length * Width
Here, L = 5/12
W = 2/3

Substitute it into the expression,
A = 5/12 * 2/3
A = 10/36
A = 5/18 ft²

So, the area of the wood would be 5/18 ft²

Hope this helps!
