Answer:
B. 11/18
Step-by-step explanation:
Solve using algebra.
x = 0.611111...
10x = 6.111111...
10x - x = 6.111111.. - 0.61111111..
9x = 5.5
x = 5.5/9
x = 11/18
draw a rectangle triangle :
sin B=8/17 that means that de biggest side are 17 ("hipotenusa"), and another side is 8. Applying de theorem of pythagoras:
![17^{2} =8^{2} +x^{2} \\x^{2} =17^{2} -8^{2}\\x=\sqrt{17^{2} -8^{2}} \\x=5\sqrt{5}](https://tex.z-dn.net/?f=17%5E%7B2%7D%20%3D8%5E%7B2%7D%20%2Bx%5E%7B2%7D%20%5C%5Cx%5E%7B2%7D%20%3D17%5E%7B2%7D%20-8%5E%7B2%7D%5C%5Cx%3D%5Csqrt%7B17%5E%7B2%7D%20-8%5E%7B2%7D%7D%20%5C%5Cx%3D5%5Csqrt%7B5%7D)
