Astop sign is in the shape of a regular octagon. what is the measure of each angle on the sign?
a. 115
b. 170
c. 135
d. 120

To calculate the angles inside a regular octagon, you have to use the formula: (number of sides -2) x 180
(n-2) x 180
(8-2) x 180

so 8-2 is 6 and 6 x 180 = 1080
Because all of the angles in a regular octagon are congruent (the same), if you divide 1080 by 8, you will get each angle

= 135

40%=2/550=1/230=3/1056=14/25
