Answer:
65°
Step-by-step explanation:
To obtain Angle A, we use the cosine rule ;
Cos A = (b² + c² - a²) / 2bc
Cos A = (12² + 14² - 14²) / 2(12)(14)
Cos A = 144 / 336
A = Cos^-1(144/336)
A = 64.62°
A = 65°
Answer: B

Step-by-step explanation:
Answer:
-3
Step-by-step explanation:
You cannot simplify this question anymore, for it is already a whole number.
Steps:
-3/1
Eliminate the fraction bar and one...
-3
(Anything over one, is whole...so if I were to put 98384743/1, it would just be 98384743.)
