2 over -1 im pretty sure that's it we just learned this like 2 weeks ago
The answer would be de = 14x but i’m not fully confident in the answer
Answer:
The first one
Step-by-step explanation:
Answer:
![Cos(C) = \frac{40}{41}](https://tex.z-dn.net/?f=%20Cos%28C%29%20%3D%20%5Cfrac%7B40%7D%7B41%7D%20)
Step-by-step explanation:
Ratio of Cos C using the trigonometric ratios formula, would be:
![Cos(C) = \frac{adjacent}{hypotenuse}](https://tex.z-dn.net/?f=%20Cos%28C%29%20%3D%20%5Cfrac%7Badjacent%7D%7Bhypotenuse%7D%20)
Adjacent = BC = 40
Hypotenuse = AC = 41
Plug in the values
![Cos(C) = \frac{40}{41}](https://tex.z-dn.net/?f=%20Cos%28C%29%20%3D%20%5Cfrac%7B40%7D%7B41%7D%20)
