Which of the following statements apply to a polygon with eight sides? i. it is a hexagon ii. it is a heptagon iii. it is an octagon iv. it has a total interior angle measure of 1,080º v. each interior angle is 135º

Options 3, 4 and 5 are the right answer.

Step-by-step explanation:

A polygon with eight sides is called an octagon.

The sum of the interior angles of an octagon is 1080 degrees. In octagon, all sides are congruent and all interior angles are congruent.

The measure of the interior angle of a regular octagon is 135 degrees.

We can find this by : degrees.

The correct options are :

iii. It is an octagon

iv. It has a total interior angle measure of 1080 degrees.

v. Each interior angle is 135 degrees.

x/3-10=8

x/3=18

x=48

the final amount you will pay is $68.04.

the tip is determined by the pre-tax amount, so we calculate the tip based on the original bill, not after we've added sales tax.

to find the tip:

we can divide 54.00 by 100 to get 1% of 54. then we multiply that by 18.

54 / 100 = .54

.54 x 18 = 9.72

tip = 9.72$

to find the tax:

we can divide 54.00 by 100 to get 1% of 54. then we can multiply that by 8 to get 8%.

54 / 100 = .54

.54 x 8 = 4.32

tax= 4.32

now we can add the tip and tax to the bill to get our total.

54 + 9.72 + 4.32 = 68.04

total: $68.04
