Answer:
z =86
Step-by-step explanation:
The exterior angle of a triangle is the sum of the opposite interior angles
z + z-39 = z+47
2z-39 = z+47
Subtract z from each side
z-39 = 47
Add 39 from each side
z = 47+39
z =86
I'll do number 11 for you
Area of a sector can be found using
A = (πr²)C/360 where C is the measure of your central angle
![A = \pi (6^{2} )( \frac{75}{360} )](https://tex.z-dn.net/?f=A%20%3D%20%20%5Cpi%20%20%286%5E%7B2%7D%20%29%28%20%5Cfrac%7B75%7D%7B360%7D%20%29)
A ≈ 23.56 m²
Oh, I guess rounded to the nearest tenth is 23.6
Hello.
In order to convert this equation into slope intercept form, we need to divide the entire equation by 7:
![\tt{8x-7y=13](https://tex.z-dn.net/?f=%5Ctt%7B8x-7y%3D13)
![\tt{\displaystyle\frac{8x}{7} -\frac{7y}{7}=\frac{13}{7}](https://tex.z-dn.net/?f=%5Ctt%7B%5Cdisplaystyle%5Cfrac%7B8x%7D%7B7%7D%20-%5Cfrac%7B7y%7D%7B7%7D%3D%5Cfrac%7B13%7D%7B7%7D)
Simplify:
![\tt{\displaystyle\frac{8x}{7}-y=\frac{13}{7}](https://tex.z-dn.net/?f=%5Ctt%7B%5Cdisplaystyle%5Cfrac%7B8x%7D%7B7%7D-y%3D%5Cfrac%7B13%7D%7B7%7D)
Add y to both sides:
![\Large\boxed{\sf{y=\displaystyle\frac{8x}{7} -\frac{13}{7}}}](https://tex.z-dn.net/?f=%5CLarge%5Cboxed%7B%5Csf%7By%3D%5Cdisplaystyle%5Cfrac%7B8x%7D%7B7%7D%20-%5Cfrac%7B13%7D%7B7%7D%7D%7D)
I hope it helps.
Have an outstanding day. :)
