vertical 7 and 4

supplementary 5 and 1

1. vertical angles: <2 and <5

2. Supplementary angles: <6 and <2

Step-by-step explanation:

Vertical angles are angles that are opposite to each other

-they will always have the same measure

-examples from the picture: 2 and 5, 6 and 1, 3 and 8, 7 and 4

Supplementary angles are angles that add up to 180

-they will always be able to form a straight line

-examples from the picture: 1 and 5, 6 and 2, 1 and 2, 5 and 6, 3 and 7, 7 and 8, 3 and 4, 8 and 4

in problems involving proportions, we can use cross products to test whether two ratios are equal and form a proportion. to find the cross products of a proportion, we multiply the outer terms, called the extremes, and the middle terms, called the means.

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
