1. To find the sales tax rate you can set up the equation:
1200x = 72; divide both sides by 1200
x = 0.06
The tax rate is 6%.
2. 6% of 2500
0.06 x 2500 = $150
For Part A, the answer is d.
3. 6% of x is $108
0.06x = 108; divide both sides by 0.06
x = 1800
The answer for Part B is letter d.

We are asked to find the slope of this graph; we are provided with two points:
![\star~\mathrm{(6,0)}](https://tex.z-dn.net/?f=%5Cstar~%5Cmathrm%7B%286%2C0%29%7D)
![\star~\mathrm{(0,-5)}](https://tex.z-dn.net/?f=%5Cstar~%5Cmathrm%7B%280%2C-5%29%7D)
![\triangle~\fbox{\bf{KEY:}}](https://tex.z-dn.net/?f=%5Ctriangle~%5Cfbox%7B%5Cbf%7BKEY%3A%7D%7D)
- What we need in order to find the slope are two points and the slope formula.
Here's the formula:
![\star~\boxed{\mathrm{\cfrac{y2-y1}{x2-x1}}}](https://tex.z-dn.net/?f=%5Cstar~%5Cboxed%7B%5Cmathrm%7B%5Ccfrac%7By2-y1%7D%7Bx2-x1%7D%7D%7D)
Where
y2 and y1 are y-coordinates
x2 and x1 are x-coordinates
Substitute the values:
![\star~\mathrm{\cfrac{-5-0}{0-6}}}](https://tex.z-dn.net/?f=%5Cstar~%5Cmathrm%7B%5Ccfrac%7B-5-0%7D%7B0-6%7D%7D%7D)
Simplify!
![\star~\mathrm{\cfrac{-5}{-6}}}](https://tex.z-dn.net/?f=%5Cstar~%5Cmathrm%7B%5Ccfrac%7B-5%7D%7B-6%7D%7D%7D)
Simplify more!
![\star~\mathrm{\cfrac{5}{6}}](https://tex.z-dn.net/?f=%5Cstar~%5Cmathrm%7B%5Ccfrac%7B5%7D%7B6%7D%7D)
Hope it helps you out! :D

Answer:
L
Step-by-step explanation:
interior angle formula so
(number of sides - 2)*180
2*180 = 360
you can also just take an example from a square 4*90 = 360
360-121-58-70 = 111
