We are given with 90<x<180 degrees and asks for the value of sin(x/2), cos(x/2) and tan(x/2). We just substitute the maximum and minimum angle to the equations. sin (180/2) is equal to 1 and sin (90/2) is equal to
![\frac{ \sqrt{2} }{2}](https://tex.z-dn.net/?f=%20%5Cfrac%7B%20%5Csqrt%7B2%7D%20%7D%7B2%7D%20)
to 1. cos (x/2) is equal to 0≤y≤<span>

Answer: The percentage of the votes were in favor of the new speed limit = 100%
Step-by-step explanation:
Given: Total votes = 17
Total votes favored the new speed limit = 17
The percentage of the votes were in favor of the new speed limit ![=\dfrac{\text{Number of votes in favor}}{\text{Total votes}}\times100\\\\=\dfrac{17}{17}\times100\%=100\%](https://tex.z-dn.net/?f=%3D%5Cdfrac%7B%5Ctext%7BNumber%20of%20votes%20in%20favor%7D%7D%7B%5Ctext%7BTotal%20votes%7D%7D%5Ctimes100%5C%5C%5C%5C%3D%5Cdfrac%7B17%7D%7B17%7D%5Ctimes100%5C%25%3D100%5C%25)
Hence, the percentage of the votes were in favor of the new speed limit = 100%
