BRAINLIESTTT ASAP! PLEASE HELP ME :)

See below.

Step-by-step explanation:

Use the compound angle identity:

sin(A - B) = sinA cosB - cos A sin B.

Plugging in the given angles:

A = 360 and B = O so:

sin (360 - O) = sin 360 cos O - cos 360 sin O

sin 360 = 0 and cos 360 = 1  therefore we have  

0 * cos O - 1 * sin O

= 0 - sin O

= -sin O.

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

any options?
