Need an explanation in this problem

The line from Y to W bisect the angle W.

Half the angle of W is given as 56 degrees,

so the full angle of W is 56 x 2 = 112 degree.

In a rhombus opposite angles equal each other, so angle Y would equal angle W.

This means angle XYZ is 112 degrees.

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
