K = 4 3k = 12 or 3*4 = 12
4k = 16 or 4*4= 16

Find the measure of the indicated angle to the nearest degree

icang [17]

Answer:

A) 18°

Step-by-step explanation:

To find the measure of the indicated angle, we can use trigonometric ratios.

Looking at the triangle, we can see that we are given the lengths of the two legs of the triangle, but not the hypotenuse. Since we are not given the hypotenuse, the sine and cosine ratios would not work since both of them require the length of the hypotenuse. We can use the tangent ratio, since it only requires the lengths of the two legs. Remember:

$tan(?)=\frac{opposite}{adjacent}$

From looking at the image, we can see that the length of the side opposite to the angle is 3, and the length of the side adjacent to the angle is 9. Thus, we can use 3 as out opposite and 9 as out adjacent:

$tan(?)=\frac{3}{9}$

Now we solve for ?. Lets take the inverse tan of both sides to get rid of the tan on the left side:

$?=tan^{-1}(\frac{3}{9})$

And we get:

? ≈ 18.4349488° ≈ 18°

So the answer would be 18°, or A.

I hope you find my answer to be helpful. Happy studying.

PLZ help me super really really fast

maria [59]

Answer:

A. 3 cm

Step-by-step explanation:

The smallest face has the sides 4 cm and 8 cm. If the water is 4 cm from its top, then the height of the water is $16-4=12$ cm and the volume of the water is

$V_{water}=4\cdot 8\cdot 12=384\ cm^3$

The largest face has the sides 8 cm and 16 cm. If the container is placed on its largest face, then the volume of the water is

$V_{water}=8\cdot 16\cdot h \ cm^3,$

where h is the height of the water.

Equate volumes of the water:

$8\cdot 16\cdot h=384\\ \\h=\dfrac{384}{8\cdot 16}=3\ cm$

Therefore, the water is 3 cm from the bottom.

How much would it cost to buy 3 medium sodas and 2 hot dogs

Vesnalui [34]

To start off you need to figure out how much money each item costs. Now get out your calculator because it will make this process go much faster.

EXAMPLE:

If your sodas cost $2.25 EACH you need to do the following math equation

2.25 X 3 = 6.75 witch is the total you would be paying in this situation.

HOT DOGS EXAMPLE:

Lets say that your hotdogs are $4.75 PER DOG. You just need to follow the same steps above.

4.75 X 2 = 9.5 but thats not how we write money so it would be $9.50

Hope this helps,

Daniel
