Which of the following side measurements could make an equilateral triangle and isosceles triangle?
a.12, 12, 14
b. 4, 5, 6
c. 2, 2, 2
d. 2, 2, 4

step-by-step explanation:

circumference divided by 3.141592654 then timesthe radius twice

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).
