If it's a cube, each side (6 sides) is 8x8. So 8x8 is 64, 64 times 6 is 384 square inches. Does that seem right to you??
Value of x is 1
Step-by-step explanation:
- Step 1: Given that ABCD is a rectangle, its diagonals bisect each other. So BE = ED
⇒ 2x + 4 = 7x - 1
⇒ -5x = -5
⇒ x = 1
Answer:
17.9140127389 FT²
Step-by-step explanation:
Circumference is found using the formula 2πr.
15=2πr
r=15/(2*3.14)
r=2.38853503185
Area is found using the formula πr²
A= πr²
=3.14( 2.38853503185²)
=17.9140127389
Answer:
180.
Step-by-step explanation:
Given
x = 1%2F2y
x+y=180
...
Substitute x into the second equation and solve for y, the larger angle
1%2F2y + y = 180
Multiply both sides by 2 to be rid of the fraction
y + 2y = 360
3y = 360
highlight_green%28y=120%29

Decoding the LaTeX that didn't render, we seek sum of the angles of the seventh roots of

That's on the unit circle, 45 degrees into the third quadrant, aka 225 degrees.
The seventh roots will all be separated by 360/7, around 51 degrees. The first seventh root has

That's around 32 degrees.
The next angle is

The next one is

and in general


The first sum is just -135° since it's one seventh of the sum of seven -135s.
We have 1+2+3+4+5+6+7 = (1+7)+(2+6)+(3+5) + 4 = 28 so

If I didn't screw it up, that means the answer is
Answer: 1305°
