Need i’ll give brainiest or whatever it’s called

∠1 = 144°

∠2 = 144°

∠3 = 36°

∠4 = 90°

∠5 = 144°

∠6 = 36°

∠7 = 144°

∠8 = 90°

Step-by-step explanation:

Line n is a straight line. The sum of the angles on a straight line is 180 degrees. It means that

∠7 + 36 = 180

∠7 = 180 - 36 = 144 degrees

Vertically opposite angles are equal. It means that

∠3 = 36 degrees

∠5 = ∠7 = 144 degrees

Since line m and line n are parallel lines, corresponding angles are equal.

∠5 and ∠2 are corresponding angles. Therefore

∠2 = ∠5 = 144 degrees

∠6 and ∠36 are corresponding angles. Therefore

∠6 = 36 degrees

∠6 + ∠1 = 180 degrees

∠1 = 180 - 36

∠1 = 44 degrees

∠8 + 90 = 180

∠8 = 180 - 90

∠8 = 90 degrees

∠4 + 90 = 180

∠4 = 180 - 90

∠4 = 90 degrees

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
