In A x=64 bc alternate interior angles are congruent and 128/2= 64. In B x=75 bc alternate exterior angles are also congruent and (151-1)/2 = 75. In C x=12 bc consecutive interior angles are supplementary. 7x+24+72=180 180-72-24=84 84/7=12

<span> $\sqrt{3}(h-3000)=h$
</span> $(\sqrt{3}h-\sqrt{3}(3000)=h$
$(\sqrt{3}-1)h=\sqrt{3}(3000)$
$h=\frac{\sqrt{3}(3000)}{(\sqrt{3}-1)}$
$=\frac{\sqrt{3}(3000)}{(\sqrt{3}-1)}$
$=7098.076$ (approximately)

The area of a face of a cube is 144cm^2 . find its volume

love history [14]

Step-by-step explanation:

1 face area = length x width (aka length x length since cube)

therefore 1 side = ±√144 cm = 12 cm or - 12cm (rej as length > 0cm)

volume = length x width x height = 12 x 12 x 12 = 1728cm^3

What happens when an image is reflected over y = -x

notka56 [123]

Answer:

Well, it's pretty simple. If your reflecting something over the y axis the X will change if it's negative or positive. So if it's -x and you flip it over it becomes a positive x. If you flip it over the x-axis the Y is the one that change to a negative or positive.

So if the shape flips over the y-axis, the X points will turn negative. for example, one of the points is (1,4) it will turn to (-1,4)

What is the solution to the system of equations below? y = negative one-third x + 6 and x = –6

PSYCHO15rus [73]

Answer:2

26x + y = 23 → y = 23 – 6x.

7x + y = 25 → 7x + (23 – 6x) = 25 → x + 23 = 25 → x = 2
