Answer:

angle 1 should equal to 54.

angle 2 should equal to 126.

Step-by-step explanation:

2x - 8 + 4x + 2 = 180

2x + 4x - 8 + 2 = 180

6x - 6 = 180

6x - 6 + 6 = 180 + 6

6x = 186

6x ÷ 6 = 186 ÷ 6

x = 31

---------------------------------------------

2x - 8 = A1

2(31) - 8 = A1

62 - 8 = A1

54 = A1

-----------------------------------------------

4x + 2 = A2

4(31) + 2 = A2

124 + 2 = A2

126 = A2

Alja [10]

To find the answer, multiply the decimal by 10. 0.05 X 10 = 0.5, and since 0.05 goes into 0.5 10 times, it is equivalent to 1/10th of 0.5.

Zoe Paid $18.60 in sales tax and tips for her dinner the sales tax rate is 11% and she tipped 20%

barxatty [35]

Answer:

The cost of the dinner before other costs is $14.20

Step-by-step explanation:

To solve this, we write the following equation:

x + .11x + .20x = 18.60

This is because in addition to paying for the dinner (x), she also has to pay 11% of it and another 20% of it. Now we can combine like terms and solve.

1.31x = 18.60

x = 14.20
