1) d. All of the above are true

2) b. 21.8°

3) 7x + 10 = 150 ; x = 20°

4) b. The measure of angle B is 117°

Step-by-step explanation:

1) 4x + 8x = 180

12x = 180

x = 15°

4x = 60°

8x = 120°

2) x = 90 - 68.2

x = 21.8°

3) 7x + 10 = 150

(Vertically opposite angles)

7x = 140

x = 20°

4) Angle A = 180 - 90 - 27

Angle A = 63°

Angle B = 180 - 63

Angle B = 117°

Angle C = 180 - 117

Angle C = 63°

step-by-step explanation:

total amount of money that he should pay if he has not used his duty free exemption is $98

step-by-step explanation:

given a united states citizen returning to the states declares the following items at the customs office: 3 shirts at $8.50 each 2 dresses at $27.50 each 1 pair of gold cuff links at $17.50 per pair. we have to find how much he pay

cost of 3 shirts if one cost at $8.50 is

cost of 2 dresses if one cost at $27.50 is  

cost of 1 pair of gold cuff at $17.50

so, total amount of money that he should pay if he has not used his duty free exemption is   $25.5+$55+$17.50=$98
