Which term best describes a major arc of a circle that has the same starting and ending point
a. circumfrence
b. diameter
c. radius
d. chord

a) Circumference

Step-by-step explanation:

Given that a major arc of the circle has the same starting and ending point.

If we start from any point A on the circumference of the circle, we see that minor arc is a point with length 0. Major arc is the length of arc measured along the circle to the same point again hence this is circumferenc.

Hence answer is

a) Circumference

(23*2)-12=x     x=34

step-by-step explanation:

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).
