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 .

a² + b²= c²

24² + 7² = c²

c= 25
