Answer:

Step-by-step explanation:

Givens

You have the hypotenuse: 13

You seek the adjacent side: x

You have the angle enclosing the 2: 47 degrees.

The relationship is the Cosine

Solution

Cos(47) = opposite / hypotenuse

Cos(47) = 0.6820                            From your calculator

Cos(47) = x / 13                                Multiply both sides by 13

13*cos(47) = x

x=8.866

5 ___ square 18 <br><br> = <br><br> &lt; <br><br> &gt;
babymother [125]

18 squared is 324, not sure if you are supposed to simplify it i'm guessing maybe. If yes then it is 3 √ 2 or 4.24264068... If not well obviously 324 is greater than 5.


So the answer would be ( > ) because 5 is bigger than 4.24....

The perimeter of a parallelogram is 72 meters. The width of the parallelogram is 4 meters less than its length. Find the length
Sidana [21]

Answer:

length = 20 mt

Width = 16 mt

Step-by-step explanation:

Let the length of the field be x

width of the field be y

Hence  formula of the perimeter is given as

P=2(x+y)

P=72(given)

72=2(x+y)

Dividing both sides by 2 we get

x+y=36---(A)

Also given that width of the parallelogram is 4 meters less than its length

Hence  

y=x-4

or x-y=4 ---(B)

Adding A and B  

2x=40

x=20

y=x-4

y=20-4=16

Hence length = 20 mt

Width = 16 mt
