Ashooting star forms a right triangle with the earth and the sun, as shown below: a right triangle is shown with the vertices labeled earth, sun, and shooting star. the angle formed by the sun is labeled x degrees and the side between the earth and the sun is labeled y. a scientist measures the angle x and the distance y between the earth and the sun. using complete sentences, explain how the scientist can use only these two measurements to calculate the distance between the earth and the shooting star.

Step-by-step explanation:

The scientist can use only the angle x and the distance y to calculate the distance between the Earth and the Sun using the cosine function.The cosine of an angle is equal to the ratio of the length of the adjacent side and the length of the hypotenuse. In equation form:cos x = BC / ySolving for BCBC = y cos xBC is the distance between the Earth and the Sun

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

answer: the answer is one

step-by-step explanation:

pemdas, in this situation there is no parenthesis or exponents so you go to multiplication, 1x1=1, then division 1/1= 1 then addition 1+1=2 then subtraction 2-1=1
