The equation m= 19.32v can be used to find the mass m in grams of a pure gold coin with volume v in cubic centimeters. Carl has a coin with a mass of 37.8 grams. the coin's volume is 2.1 cubic centimeters. Be a math detective and decide if the coin could be pure gold. Explain your reasoning.

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).

if you are looking for the unit rate then the answer would be 9 because unit rate is distance divided by time.
