Which pair of these numbers has 20 as a common factor?
2 and 3
2 and 6
20 and 40

20 and 40

Step-by-step explanation:

3x7 is 21 but thats only one too much it has to be 3 too much to go down one and be a factor

6x4 is 24 it has to be 6 too much to go down one to be a factor

20x1 and 40x1/2 are both factors unless your teacher doesn't include fractions, so just choose this for now and if you get it wrong ask your teacher because three and six arent

898.1666667

step-by-step explanation:

5389/6 = 898.1666667

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).
