This is a lot of calculation.

So we know that the sum of angles for any heptagon is 900, because heptagon can be divided into five non-overlapping triangles and sum of angles of each triangle is 180.

Now you just add up all angles and simplify the equation:

900 = (6x - 8) + 120 + (7x - 64) + (5x - 4) + 135 + (3x + 31) + (4x + 15)

900 = <span>25x + 225

Now it's just regular algebra equation. You can solve for x:

675 = 25x

x = </span>27

So the value of x is 27

Which of the following is least?
Olegator [25]
In order from least to greatest, it's listed as:

0.015, 0.105, 0.15, 0.501.

0.015 is the lowest number because it is the farthest from being a whole. It starts with .0, whereas the rest of them have a number higher than 0 after the period.

can some one answer this for 100 points and brainlessly can someone write it out on paper so i can copy it you have to find the
const2013 [10]

Answer:

<em>14 </em>° <em>;</em> <em>83 </em>°

Step-by-step explanation:

( 14x - 1 )° + ( 2x + 2 )° = 97°

14x - 1 + 2x + 2 = 97

16x = 96

x = 6

m∠BCA = ( 2 × 6 + 2 )° = <em>14 </em>°

m∠ABC = ( 14x - 1 )° = <em>83 </em>°

What is 0.467 + 0.025?<br> O A. 0.442<br> B. 0.4695<br> C. 0.492<br> OD. 0.717
enyata [817]

Answer:

C. 0.492

Step-by-step explanation:

All I did was add the two numbers. Add them like normal, even though they are in decimal form. You could also use a calculator. If you don't have one, there should be one programed into your phone and computer.

  0.467

+ 0.025

= 0.492

I hope this helps! Please let me know if you have any more questions or need any more help. Have a great day!
