X²-18x+81 + y²+8y+16 = -5+81+16=92
(x-9)² + (y+4)² = (2✓23)²
circle centered at (9,-4) with radius 2✓23
Cups or Liters <em />I would hope!
Hope this helps!!
Answer: number 2
Step-by-step explanation: so a supplementary Angle adds up to a 180 angle so it would be number 2 I think.
Answer: ZAFB
Step-by-step explanation:
Answer: 40º
Step-by-step explanation:
To find angle c, not give 2 angles at least, we must use a trigonometric function. With respect to angle c, we can see that we have the opposite and adjacent sides.
The trigonometric function that relates opposite and adjacent sides is tangent.
![tan=\frac{opposite}{adjacent}](https://tex.z-dn.net/?f=tan%3D%5Cfrac%7Bopposite%7D%7Badjacent%7D)
![tan=\frac{21}{25}](https://tex.z-dn.net/?f=tan%3D%5Cfrac%7B21%7D%7B25%7D)
![tan^-^1=40](https://tex.z-dn.net/?f=tan%5E-%5E1%3D40)
