Select the correct answer. A
(12x + y + z = 26
x-11y = 17
x - y + 4z =23
B
4x + y + z = 23
x-11y = 17
x - y + 12z = 26
с
(x + y + z = 4
x-y=11
x - y + z = 12
( x + y + z = 12
x - y = 11
x-y + z = 4

correct answer:

b.(19,-2)

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).
