The sum of everything is 720 degrees, because of the six sides in this figure.
We sum all angles and get 595
720 - 595 = 125
The answer is 125 degrees
Answer:
the answer is x^12
Step-by-step explanation:
multiply 3 by 4 and you get 12
Ignoring the "?" in your question:
![5k+10k+6=0 \iff 15k+6=0 \iff k=-\dfrac{6}{15}](https://tex.z-dn.net/?f=5k%2B10k%2B6%3D0%20%5Ciff%2015k%2B6%3D0%20%5Ciff%20k%3D-%5Cdfrac%7B6%7D%7B15%7D)
If the "?" is a squared symbol that wasn't caught:
![5k^2+10k+6=0](https://tex.z-dn.net/?f=5k%5E2%2B10k%2B6%3D0)
Use the quadratic formula
![x_{1,2}=\dfrac{-b\pm\sqrt{b^2-4ac}}{2a}](https://tex.z-dn.net/?f=x_%7B1%2C2%7D%3D%5Cdfrac%7B-b%5Cpm%5Csqrt%7Bb%5E2-4ac%7D%7D%7B2a%7D)
to get the solutions:
![x_{1,2}=\dfrac{-10\pm\sqrt{100-120}}{10}](https://tex.z-dn.net/?f=x_%7B1%2C2%7D%3D%5Cdfrac%7B-10%5Cpm%5Csqrt%7B100-120%7D%7D%7B10%7D)
as you can see, the discriminant is negative, so the equation has no solution.
The slope of <em>y</em> = 2<em>x</em> - 5 is 2. Parallel lines have the same slope, so the slope of the line through the given points <em>A</em> and <em>B</em> is also 2. This means
(8 - 4) / (6 - <em>n</em>) = 2
Solve for <em>n</em> :
4 / (6 - <em>n</em>) = 2
4/2 = 6 - <em>n</em>
2 = 6 - <em>n</em>
<em>n</em> = 6 - 2
<em>n</em> = 4
