Answer:
A = - 2n - 1
Step-by-step explanation:
A=-3+(n-1)(-2)
<=> A = - 3 - 2(n-1)
<=> A = - 3 - 2n -2×(-1)
<=> A = - 3 - 2n + 2
<=> A = - 1 - 2n = - 2n - 1
The Cosine Law:
c² = a² + b² - 2 a b cos C
14² = 28² + b² - 56 · b · √3/2
196 = 784 + b² - 28√3 b
b² - 28√3 b + 588 = 0
b 1/2 = (28√3 +/- √(2352 - 2352 )) / 2 = 28√3 / 2 = 14√3
