Answer:
The answer is C. AAA is not a congruency postulate because the side lengths may be different sizes although the angles are the same.
Let r be a radius of a given circle and α be an angle, that corresponds to a sector.
The circle area is
![A=\pi r^2](https://tex.z-dn.net/?f=A%3D%5Cpi%20r%5E2)
and denote the sector area as
![A_1](https://tex.z-dn.net/?f=A_1)
.
Then
![\dfrac{A_1}{A}= \dfrac{\alpha}{2\pi}](https://tex.z-dn.net/?f=%20%5Cdfrac%7BA_1%7D%7BA%7D%3D%20%5Cdfrac%7B%5Calpha%7D%7B2%5Cpi%7D%20)
(the ratio between area is the same as the ratio between coresponding angles).
![A_1=\dfrac{\alpha}{2\pi} \cdot A=\dfrac{\alpha}{2\pi} \cdot \pi r^2= \dfrac{r^2\alpha}{2}](https://tex.z-dn.net/?f=A_1%3D%5Cdfrac%7B%5Calpha%7D%7B2%5Cpi%7D%20%5Ccdot%20A%3D%5Cdfrac%7B%5Calpha%7D%7B2%5Cpi%7D%20%5Ccdot%20%5Cpi%20r%5E2%3D%20%5Cdfrac%7Br%5E2%5Calpha%7D%7B2%7D%20)
.
Step-by-step explanation:
AB = 3
by similaritiy criterion
CE/ CB= ED/AB
4/6= 2/AB
AB = 3

Answer:
The domain is the set of x values for which the function resides in.
In this graph, it is unclear as to if the function goes on to infinity, but if it does, the answer is quite easily:
(-2, 4] and [7, ∞)
since the function starts on the left at -2 then continues to the right, with a pause, then indefinitely after.

</u> 36.125 (rounded up is 36.13)
