Answer:
90.4°
Step-by-step explanation:
Use Law of Cosines to solve:
12² = 9² + 8² - 2(9)(8)Cos X
144 = 81 + 64 - 144Cos X
-1 = -144Cos X
-1/144 = Cos X
Cos^-1 (-1/144) = X
X = 90.39789056°
Answer:
I would say the answer is C
Tan(30o)= ?/25
25 * tan(30o) = ?
? = 14.4
More than likely it is c, because I looked over all the answers and c was the best one for the problem
I think it is 1 because it is smaller than 1.5 so it would have to be 1
