We can use trigonometry.  The cosine of 15 will be the side adjacent to the 15-degree side (the one we are looking for) divided by 20, the hypotenuse.  As cos(15) is about .966, we get 19.32 as the side we are looking for.

Ramond is putting a fence around his rectangular garden shown above. Before he can build the fence, he needs to find the perimet
solniwko [45]

The gardens perimeter is 12 meters.

Explanation:

  • The garden has a 4m length and a 2m width. The perimeter of any given rectangle is two times the sum of the length and the width of the same rectangle.
  • Perimeter = 2 × (length of the rectange + width of the rectangle)

        Perimeter = 2 × (4m + 2m) = 2 × (6m) = 12 meters.

  • So the gardens perimeter is equal to 12 meters.
  • Ramond needs to buy a fence for a garden whose parameter is 12 meters.

What is the value of x?
solniwko [45]

Answer:

x = 7.5

Step-by-step explanation:

Since we see that sides AD and DC are equal, as well as sides BE and EC, we can use this information to conclude that the value of 2x-7 is equal to double the value of DE.

2x - 7 = 4(2)

2x - 7 = 8

2x - 7 + 7 = 8 + 7

2x = 15

x = 7.5

What is 0.5 repeating as a fraction in simplest form
Solnce55 [7]

Answer:

5/9

Step-by-step explanation:

Start be letting x = 0.555...

Our original equation is:

x = 0.555...

There is only one digit repeating, the 5, so we multiply both sides of that equation by 10 and write it above the original equation.

10x = 5.555...

   x = 0.555...

Now we subtract the second equation from the first equation as written above.

9x = 5

Divide both sides by 9.

x = 5/9

0.555... = 5/9
