Answer:
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
.
