Answer:
![x = \sqrt{32}](https://tex.z-dn.net/?f=x%20%3D%20%5Csqrt%7B32%7D)
Step-by-step explanation:
![\frac{4}{x} - \frac{x}{8} = 0\\\\\frac{4}{x} = \frac{x}{8}\\\\x^2 = 32\\\\x = \sqrt{32}](https://tex.z-dn.net/?f=%5Cfrac%7B4%7D%7Bx%7D%20-%20%5Cfrac%7Bx%7D%7B8%7D%20%3D%200%5C%5C%5C%5C%5Cfrac%7B4%7D%7Bx%7D%20%3D%20%5Cfrac%7Bx%7D%7B8%7D%5C%5C%5C%5Cx%5E2%20%3D%2032%5C%5C%5C%5Cx%20%3D%20%5Csqrt%7B32%7D)

Answer: 83
Step-by-step explanation: 17% of 500 is 85. If 17% is empty, that means that you'd take away that 15%. 500 - 85 = 415. If each page holds 5 cards, we need to split those cards up between the pages. 415/5 = 83, so 83 pages will be used.
90°-77°=13°.
the answer is 13°
