The regular octagon has a perimeter of 122.4 cm. which statements about the octagon are true? check all that apply.

The length of segment XY can be found by solving for a in

The measure of the central angle is .

Step-by-step explanation:

If the regular octagon has a perimeter of 122.4cm, then each side is

The measure of each central angle is

The angle between the apothem and the radius is

The segment XY=a is the height of the right isosceles triangle.

We can use the Pythagoras Theorem with right triangle XYZ to get:

Therefore, the correct options are:

The length of segment XY can be found by solving for a in

The measure of the central angle is .

option a.

step-by-step explanation:

if you look closely at the graph, we can notice that the function is not defined at two different points.

if you look at functions b and c, you will notice that both functions are not defined at just one point. the function b is not defined at x= -5/2 and function c is not defined at x=-5. both options are discarded, given that our function should not be defined at two fiferent points.

now, if you look closely at the graph you will notice that the function sketched is not defined at x=5 and x=-2.
