x = 2
x = -21
Step-by-step explanation:
I think it’s B. since it’s on the adjacent & hypotenuse side it makes it cosine, and the correct way to set it up is B i believe. hopefully i’m not wrong because it could also be D
Answer:
222 fence posts
Step-by-step explanation:
Since the log is 20 m long, correct to the nearest metre and has to be cut into fence posts which must be 90 cm long, correct to the nearest 10 centimetres, there can be x fence posts 90 cm long.
So, we have x × 90 cm = 20 m
x × 0.9 m = 20 m
x = 20 m/0.9 m
x = 222.22
x ≅ 222 fence posts
So, the largest number of fence posts that can possibly be cut from the log is 222 fence posts.
