Which equations show the associative property?
select each correct answer.
(a)(−8 1/1+(−1 5/6))+(−5 1/6)=(−5 1/6)+(−8 1/1+(−1 5/6))

(b)2 1/6+(−1/6+(−3 7/8))=(2 1/6+(−1/6))+(−3 7/8)

(c)(1/4+(−4/5))+(3/5)=1/4+(−4/5+3/5

) (d)2 1/2 +(-2/3+(-4 1/9))=2 1/2 –(2/3+4 1/9

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).

hope this is what you were asking for!
