The given problem is a quadrilateral shape. There are 4 angles and sides shown in the problem and the only given angle is X.

The illustration shows four sides (quad), the stick drawn at the center of each sides describes the relationship of their lengths.

All one stick are equal, and two sticks are also equal.

Given Angles:

X=102 deg
W=(7x+4) deg
Y=(5x-4) deg

Since angle X is 102 degrees, then angle Z is also 102 degrees. The total angle of a quadrilateral is 360 degrees.

So, to find x:

102 + 102 + 7x + 4 + 5x - 4 = 360
x=13

<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)

What is the surface area 1ft 1ft 1ft?

Elodia [21]

Answer:

6 ft^2

Step-by-step explanation:

If the object in question is a cube, then we could say the length is 1, the depth is 1 and the height is 1, in which case each side of the cube has an area of 1 ft^2.

There are 6 such sides, so the total surface area is 6 ft^2.

Next time please be explicit in naming the shape, either verbally or with a diagram.
