-4 and 5

Step-by-step explanation:

4*5 = x(x-1) ; cross multiply

20 = x²-x ; distribute multiplication over subtraction

x²-x-20 =0; subtract 20 from both sides

(x+4) (x-5) = 0; factor

x+4 =0 gives x = -4

x-5 =0 gives x = 5

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).
