Well the real answer is 8082 if i did this in my head i would take the 9 and multiply it by each number and there's your answer
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
.

Answer:
(3, 2), (2, 3)
Step-by-step explanation:
x + y = 5
xy = 6
Solve the first equation for x.
x = 5 - y
Substitute 5 - y for x in the second equation.
xy = 6
(5 - y)y = 6
5y - y² = 6
y² - 5y + 6 = 0
Factor.
(y - 2)(y - 3) = 0
y - 2 = 0 or y - 3 = 0
y = 2 or y = 3
Now substitute 2 for y in the first equation and solve for x.
x + y = 5
x + 2 = 5
x = 3
One solution is x = 3; y = 2, or (3, 2).
Now substitute 3 for y in the first equation and solve for x.
x + y = 5
x + 3 = 5
x = 2
Another solution is x = 2; y = 3, or (3, 2).
Answer: (3, 2), (2, 3)
