Based on the picture below:

solve for ab

AB ≈ 35.93

Step-by-step explanation:

Using the cosine ratio in the right triangle

cos3.5° = = =

Multiply both sides by 36

36 × cos3.5° = AB, thus

AB ≈ 35.93 ( to 2 dec. places)

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
