Find angle 1, angle 2, and angle 3

61° , 151° , 12°

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180° , then

∠ 1 + 29° + 90° = 180°

∠ 1 + 119° = 180° ( subtract 119° from both sides )

∠ 1 = 61°

∠ 2 and 29° are adjacent angles on a straight line and sum to 180° , then

∠ 2 + 29° = 180° ( subtract 29° from both sides )

∠ 2 = 151°

Using sum of angles in a triangle = 180°

∠ 3 + 17° + 151° = 180°

∠ 3 + 168° = 180° ( subtract 168° from both sides )

∠ 3 = 12°

step-by-step explanation:

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
