Answer:
140°
Step-by-step explanation:
The long arc intercepted by angle c is 360° -80° = 280°. The measure of inscribed angle c is half the measure of the arc it intercepts.
c = 280°/2 = 140°

I think is 12x2 +48x-27 but I'm confused
Answer:
![\large\boxed{b=\sqrt{95}}](https://tex.z-dn.net/?f=%5Clarge%5Cboxed%7Bb%3D%5Csqrt%7B95%7D%7D)
Step-by-step explanation:
Use the Pyhagorean theorem:
![leg^2+leg^2=hypotenuse^2](https://tex.z-dn.net/?f=leg%5E2%2Bleg%5E2%3Dhypotenuse%5E2)
We have
![leg=b,\ leg=7,\ hypotenuse=12](https://tex.z-dn.net/?f=leg%3Db%2C%5C%20leg%3D7%2C%5C%20hypotenuse%3D12)
Substitute:
![b^2+7^2=12^2](https://tex.z-dn.net/?f=b%5E2%2B7%5E2%3D12%5E2)
<em>subtract 49 from both sides</em>
![b^2=95\to b=\sqrt{95}](https://tex.z-dn.net/?f=b%5E2%3D95%5Cto%20b%3D%5Csqrt%7B95%7D)
Answer:
Divide a percent by 100 and remove the percent sign to convert from a percent to a decimal.
Example: 10% becomes 10/100 = 0.10.
Example: 67.5% becomes 67.5/100 = 0.675.

Answer:
a - 2
Step-by-step explanation:
Perimeter = side 1 + side 2 + side 3
So
6a + 3 = 2(a + 3) + (3a - 1) + side 3
side 3 = (6a + 3) - (2a + 6) - (3a - 1)
side 3 = 6a - 2a - 3a + 3 - 6 + 1 = a - 2
