Answer:
No Solution
Step-by-step explanation:
It does not make sense to have two different variables on the same equation.
-t + 9t - 12t - (-16t) - 18t = -6
-t + 9t - 12t + 16t - 18t = -6
-6t = -6
-6t/-6 = -6/-6 (-6 on the left side cancels out so we are only left with T and our answer)
T = 1
2/3 This is from 8/12 4/6 2/3. You just keep dividing by 2
Answer:
Law of cosine
