Answer:

The answer is 3x-27

Step-by-step explanation:

If the angles are vertical from each other it means they are congruent. 2x+30 is 63, you plug in the x, 2(30)+30. You do that to the second one and also get 63, 3(30)-27. Therefore 3x-21 is the answer.

<span>A healthy human body is approximately 18% carbon, so to determine how many pounds of carbon a 200lb body contains, compute 200lbs X 0.18 = 36 pounds. To convert 36lbs to kilograms, multiply by the conversion factor 0.454. Therefore, 36lbs X 0.454 = 16.344 kg.</span>
