Please give me an explanation or answer to this.

choice 1) (3, 12)

Step-by-step explanation:

b = 4a

if a = 3 then:

3x4 = 12

#1 is the answer

Step-by-step explanation:

2 x4=8

3 x4=12

4 x4=16

5 x4=20

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).
