This can solved using the cosine law which is: c² = a² + b² - 2ab cos θ Using the values given from the problem 6² = b² + b² - 2bb cos 112.62 And solving for b 36 = 2b² - 2b² cos 112.62 b = 3.6
if he got 84 votes 3/7 so you take 84 times 4 (i got four by subracting 3 from 7 and got the remaining votes) and you will get 336 votes. hope this helps! :)
