c² = a² + b² - 2 a b cos C
2 a b cos C = a² + b² - c²
cos C = (a² + b² - c²) / 2ab
C = arccos( (a² + b² - c²) / 2ab )
C = arccos( (17² + 8² - 16²) / (2 (17)(8) ) )
C ≈ 69.11°
Answer: 69.1
Answer:
-2
Step-by-step explanation:
Start on -5 on the left side of the number line, jump from -5 three times to the right of the number line since ( - - ) means to add. As you jump draw "bridges" and by the time you have completed the amount of jumps you have to do you'll end up with a difference of -2.
Mean: add up all numbers and divide by the number of data
12 + 12 + 7 + 5 + 10 + 16 = 62
62/6 = 10.333... (mean)
5,7,10,12,12,16
