Okay. So, I just worked out this problem with trial and error. I also think that my answer is correct. There are 12 sides in the polygon, and if it is a regular figure, it is 360*/12. So, you have (7x + 3)*. You know that 7x5=35, so 7x50=350. 350+3=353. That isn't at 360 yet. So if you multiply 51x7, you get 357, and 357+3=360. Your answer is x=51.

Which equations results from adding the equations in this system? x+6y=9 -x+2y=-15

UkoKoshka [18]

Answer:

8y = -6

Step-by-step explanation:

Simply add the equations as you would numbers.

The 'x's cancel each other out. The 'y's add together as normal numbers.

9 + (-15) = -6

Hope that this helps!

Find the cosine of ∠W.

allochka39001 [22]

Answer: 8/17

Explanation:

We'll need the pythagorean theorem to find the missing side length.

$a^2 + b^2 = c^2\\\\15^2 + b^2 = 17^2\\\\225 + b^2 = 289\\\\b^2 = 289 - 225\\\\b^2 = 64\\\\b = \sqrt{64}\\\\b = 8$

Now we can compute the cosine ratio.

cos(angle) = adjacent/hypotenuse

cos(W) = VW/UW

cos(W) = 8/17
