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:
Kenny has eaten 44 scoops of ice cream.
We know the y intercept is 16 because y=16 when x=0.
Find slope by calculating change in y over change in x.
(12-16)/(2-0)
-4/2
-2
Plug both values into slope intercept form. y=mx+b where m is slope and b is the y intercept.
Final answer: y=-2x+16
I’m sorry but I don’t know i would honestly like to help u but don’t know
