x=3. (27x+2)
x=81x+6
80x=-6
x=-3/40
Answer:
50
Step-by-step explanation:
10 + (20x2) = 50
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
The answer is the 3rd option.
