sin(45degrees) or BC/AB is 1/sqrt2(that's the value of sin45 degrees I recommend you to memorize this.)

x/12=1/sqrt2

x*sqrt2=12

x=12/sqrt2

Now rationalize this fraction to make the answer more formal.

x=12sqrt2/2(I multiplied both top and bottom by sqrt2)

Now simplify

x=6sqrt2

Question done! answer is C 6 square root of 2

Hope this helped any questions just put them in the comments.

Andrey is making a garden box and wants to know how much dirt is needed to fill the box. A prism has a length of 8 feet, height
olga_2 [115]

Answer:

The space inside the box is the volume, which is 128 ft3

Step-by-step explanation:

Given the dimensions of the box as 8ft by 2ft by 8ft. We calculate it's volume and surface area to validate the statements;

V=lwh\\\\=8\times 2\times 8\\\\=128 \ ft^3\\\\Area=2lw+2lh+2hw\\\\=2(8*2)+2(8*8)+2(2*8)\\\\=192 \ ft^2

The volume of the box is 128 ft^3 and its surface area 192 ft^2. Hence, the correct statement is The space inside the box is the volume, which is 128 ft3

I just need help with the table
navik [9.2K]
-2, 0, 2, and 4 are the x values. To find y, we must substitute x for each of these values in y = -3/2x + 2.

-3/2 times -2 = 3. 3 + 2 = 5. The y value that goes with -2 in the table is 5.

-3/2 times 0 = 0. 0 + 2 = 2. The y value that goes with 0 is 2.

-3/2 times 2 = -3. -3 + 2 = -1. The y value that goes with 2 is -1.

-3/2 times 4 = -6. -6 + 2 = -4. The y value that goes with 4 is -4.

So, the table/coordinates are:

(-2, 5)
(0, 2)
(2, -1)
(4, -4)

I hope this makes the process clear.
