Step-by-step explanation:
Answer:
9 = x^2+y^2
Step-by-step explanation:
3^2 = (x-0)^2 + (y-0)^2
9 = x^2+y^2
<h2>ANSWER:</h2><h3>Non Elements</h3><h3 /><h2>NOTES:</h2><h3>With the exception of HYDROGEN, the elements on the left side of the periodic table are METALS. Elements on the right side of the periodic table are NONMETALS.</h3>
![y = \frac{350}{tan(28^{o})} = 658.3](https://tex.z-dn.net/?f=y%20%3D%20%5Cfrac%7B350%7D%7Btan%2828%5E%7Bo%7D%29%7D%20%3D%20658.3)
You probably did 350*tan(28) instead which gave the wrong value of y.
![x = \frac{350}{sin(28^{o})} = 745.5](https://tex.z-dn.net/?f=x%20%3D%20%5Cfrac%7B350%7D%7Bsin%2828%5E%7Bo%7D%29%7D%20%3D%20745.5)
You can verify this answer by testing if the 3 values form a pythogorean triplet.
![350^{2} + 658.3^{2} = 555858.89](https://tex.z-dn.net/?f=350%5E%7B2%7D%20%2B%20658.3%5E%7B2%7D%20%3D%20555858.89)
![745.5^{2} = 555770.25](https://tex.z-dn.net/?f=745.5%5E%7B2%7D%20%3D%20555770.25)
Which gives an error ~0.1%, consistent with our 4 s.f. rounding above.
