The sum of the measures of the interior angles of a polygon with n sides is (n – 2)180.
The measure of each interior angle of an equiangular n-gon is.
If you count one exterior angle at each vertex, the sum of the measures of the exterior angles of a polygon is always 360°.
Answer:
There are 180 degrees in a triangle so it is 80 degrees

Answer:
13
Step-by-step explanation:
500(x-3)=5000
500x-1500=5000
500x=5000+1500
500x=6500 /:500
x=13
Very handy question to know the answer to. I know of no place on the planet that does not have a tax of some sort.
The tax only applies when money changes hands. It does not apply to any discounts
So if you take the deal, the cost is
Cost of 2 pizzas = normal price - the discount.
Cost of 2 pizzas = 2*10.50 - 2.00
Cost of 2 pizzas = 21 - 2
Cost of 2 pizzas = 19.00 dollars.
Not you add on the sales tax. You can do this one of two ways, the long way or the short way.
<u>Long way</u>
Find the sales tax
Tax = % * cost
Tax = (7.5/100) * 19
Tax = 1.425 don't round yet.
Total Cost = purchase + tax
Total Cost = 19.00 + 1.425 = 20.425 Now round. This is a real problem. It depends on what you have been told to do about rounding when 5 is the last digit. I round up. So my answer would be 20.43 <<<<< Answer.
<u>Short Way</u>
Cost = (Price - discount)*(1 + %/100)
Cost = (21 - 2)*(1+ 7.5/100)
Cost = 19 * (1.075)
Cost = 20.425 = 20.43
