In total the interior angles add to (8-2)*180 = 6*180 = 1080 degrees. IF the octagon is regular, so that all of its angles are equal, then each one is 1080/8 = 135 degrees.
you have to times 180 degrees by minus 2 of how many sides then divide it by how many side. 8-2=6 6x180=1080 1080divided by 8 = 135 degree is equal to 1 angle of a regular octagon. happy to help
The sum of the measure of the angles of any polygon is 180 x (the number of sides - 2). So for a triangle it is 180*(3-2) = 180 degrees. So an octagon, 8 sides, is 180 x (8-2) = 180 x 6 = 1080 degrees. This is the same whether all the angles are equal or not.
120 It is 135 degrees. ((8 x 180) - 360) / 8 = 135
If one base angle is 8°, the other base angle must also be 8°. The total of all angles for a triangle must equal 180°, so 180° - 8° - 8° = 164°.
The sum of the interior angles of any regular polygon of n sides is equal to 180(n - 2) degrees. In this instance, the sum of the interior angles of a decagon is equal to 180 x (10 - 2) = 1440 degrees.(10-2)*180 = 8*180 = 1440 degrees.
a triangle is 180 degrees a square is 2 triangles so it is 360 degrees an octagon is 8 sides 720 degrees 180 times 4 = 720 degrees
number of sides minus 2 times 180 8-2 x 180 6 x 180 1080 dg evry angle is 1080/8 dg 135 degrees

The sum of the internal angles of a n-gon are (n-2)*180 degrees. For an octagon, n = 8 so the sum of the internal angles is (8-2)*180 = 6*180 = 1080 degrees. If the octagon is regular, all eight of its internal angles are equal. So each of them equals 1080/8 = 135 degrees.
In total the interior angles add to (8-2)*180 = 6*180 = 1080 degrees. IF the octagon is regular, so that all of its angles are equal, then each one is 1080/8 = 135 degrees.

It is: 135/360 = 3/8 in its lowest terms
The number of degrees in any geometric shape is 180*(n-2) where n is equal to the number of side. Since an octagon has 8 sides, there would be 180*6 or 1080 degrees total in the entire shape.
120 It is 135 degrees. ((8 x 180) - 360) / 8 = 135
If one base angle is 8°, the other base angle must also be 8°. The total of all angles for a triangle must equal 180°, so 180° - 8° - 8° = 164°.
