Answer with Step-by-step explanation:

Shelley plans to enclose the patio with fencing.

The Part to be fenced is the perimeter of the patio-Length of the patio which is along the side of house

As we can see that:

Length of patio=12 meters (4 square grids=4×3=12)

width of patio=6 meters  (2 square grids=2×3=6)

Since, patio is in shape of rectangle hence,

Perimeter of patio=2(12+6)

                             = 36 meters

Total part to be fenced=36-12

                                     =24 meters

Cost of fencing 1 meter=$ 5

Cost of fencing 24 meters=$ (5×24)

                                         = $ 120

Hence, cost to enclose the patio is:

$ 120

$120 because the fencing of the patio would use up eight squares and each square in the picture is 3 meters so we would need 24 meters of fencing to cover up the entire patio. Since it cost $5 for one meter, 5*24 is $120.

Find the values of the variables and the measures of the angles
yuradex [85]

Answer:

x = 13

39° and 51°

Step-by-step explanation:

Angles in a triangle add up to 180 degrees.

This is a right angle triangle, so one side has a size of 90 degrees.

3x + 4x - 1 + 90 = 180

7x + 89 = 180

7x = 91

x = 91/7

x = 13

Put x as 13 to work out the size of the angles.

3(13) = 39

4(13) - 1

52 - 1 = 51

Determine the value of each variable in the figure below. Keep answers in simplest<br> radical form.
Tanzania [10]

Answer:

  a = 21

  b = 63

  c = 42√3

  d = 21√3

Step-by-step explanation:

The sides of a 30°-60°-90° triangle have the ratios 1 : √3 : 2. The given side (42) is the longest side of the smallest triangle, and the shortest side of the largest triangle.

That means the other sides of the smallest triangle will be ...

  a = 42/2 = 21

  a+b = 2(42) = 84

  b = (a+b) -a = 84 -21 = 63

  d = 21√3 . . . . middle-length side of the smallest triangle

  c = 42√3 . . . . middle-length side of the largest triangle

The values of the variables are ...

  • a = 21
  • b = 63
  • c = 42√3
  • d = 21√3
