Let the measure of an angle be 'x'
Then the reflex angle will be measured by the formula (360-x)
x +(360-x) = 360
The area of a right triangle with side lengths 7 and 7 is ![\frac{bh}{2} = \frac{7*7}{2} = \frac{49}{2} = 24.5](https://tex.z-dn.net/?f=%5Cfrac%7Bbh%7D%7B2%7D%20%3D%20%5Cfrac%7B7%2A7%7D%7B2%7D%20%3D%20%5Cfrac%7B49%7D%7B2%7D%20%3D%2024.5)
Answer:
![7 \times {3}^{n - 1}](https://tex.z-dn.net/?f=7%20%5Ctimes%20%20%7B3%7D%5E%7Bn%20-%201%7D%20)
Step-by-step explanation:
using form:
![a \times {r}^{n - 1}](https://tex.z-dn.net/?f=a%20%5Ctimes%20%20%7Br%7D%5E%7Bn%20-%201%7D%20)
where a: starting number
where r: common ratio (in this case each next term is 3 times previous term)
Answer:
2x+6-(x^2+6x+9)*pi
Step-by-step explanation:
2*(x+3) - (x+3)^2*pi
2x+6-(x^2+6x+9)*pi
um I think there are answer choices so I don't know if I have to keep going but that should be right
the answer is 38.53 becauase it is...
