Two mixtures of coffee beans in one-pound bags. A store is selling
The first mixture
has 12 ounces of Sumatra combined with 4 ounces
of Celebes Kalossi, and costs $15. The second mixture has 4 ounces
of Sumatra and 12 ounces of Celebes Kalossi, and costs $21. How
much does one ounce of Sumatra and

p ÷ r = tan(x)

step-by-step explanation:

given that there is a figure below shows a right triangle: a right triangle is shown with hypotenuse equal to q units and the length of the legs equal to p units and r units.

graph is missing so i will create the graph as per given information.

the angle between the legs having lengths p units and q units is y degrees. the angle between the legs having lengths r units and q units is x degrees.

now we need to find about what is p ÷ r equal to.

so we can use trigonometric ratio tan(x)=[altitude]/[base] to find the value of p ÷ r, because p is the altitude and r is the base.

p ÷ r=tan(x)

hence final answer is p ÷ r=tan(x).

the answer for your question is

step-by-step explanation:

2/3=10/15

1/5=3/15

10+3=13/15

2 13/15 is the answer
