Which statement is true?
(n+4) - 7 = 18
((m-1)+ 12)+0= 12
o ((+1)- 18) +11 =-28
On+(m-1)+(5+1) = -28

okay wait before i answer, is this for your points on a graph?

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).

sorry i just need to anwers this to get points
