find the cosine ratio of angle θ. hint: use the slash symbol ( / ) to represent the fraction bar, and enter the fraction with no spaces.

triangle abc is shown. ab measures 4. bc measures 5. ca measures 3. the angle formed at point c is marked theta and angle a is the right angle.

answer for blank 1:

The cosine of the angle theta is given as:

cos θ=3/5

Step-by-step explanation:

We know that cosine of any angle theta is defined as:

Where theta is the angle formed with whose respect we apply the trignometric identity. ( As we are given an right angled triangle so we can easily apply our trignometric identity)

Now here we have base=CA=3

and hypotenuse=BC=5.

Hence, cos θ=3/5

Also the figure of the question is attached to the answer.

amount of oatypop that contains the prize = 40%

amount   of oatypop which doesn't contain the prize = (100-40)=60%

probability that hannah will win a prize

    = s +f s +f f s+ff   f s+ff f f s+ infinity.where f= failure,s= success

=   or 60%

probability that hannah only has to buy 3 or less boxes before getting a prize= (s) and ( f s) and (ff s) and (f f f s)

        = = 87.04 %  

step-by-step explanation:

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
