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:
-6( 7/6) + 2( 1/3) = - (19)/(3) or 2/3 depending on your answers.
Step-by-step explanation:
Answer:
Matter in its gas state has the most thermal energy than when it is a solid or a liquid.
43/50 is easier because 50 is half of 100
Watch this
43/50. Since 50 is HALF of 100 so we multiply 2 by 50 which is 100. But since we multiplied by 2 for the denominator we have to do the same for the numerator so 43 x 2 is equal to 86.
So we get 86/100 which is 0.86
You subtract the 11 from both sides, then you get -3x = 33. Next, you divide -3 from both sides, and you get x= -11
