Cos(a) 63/65 to find sin(a) and tan(a)

Step-by-step explanation:

Sin(a) = 16/65

Tan(a) = 16/63

Step-by-step explanation:

Cos(a) = adj/hyp

opp² = 65² - 63²

Opp = 16

Sin(a) = 16/65

Tan(a) = 16/63

Assuming a is acute.

If angle is in the fourth quadrant, sin and tan will be negative

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
