The sum of angles in a regular octagon is
180*(8 - 2) = 1080°.
Each angle of the octagon is 1080/8 = 135°.
There are 8 equal central angles to each vertex.
Each central angle is 360/8 = 45°

Answer:
Therefore the octagon will map onto itself if it is rotated by its center through these angles:
45°
90°
135°
180°

What is the approximate value for 813 divided by 13 A. 30 B. 35 C. 40 D. 45

kirill115 [55]

None of the options is correct. 813 divided by 13 equals 62.538461, whose approximate value is 62

13 times 813 equals 62.538461.

813/13 produces a non-terminating, repeating decimal as a consequence.

The repeating pattern seen above, 538461, is referred to as repetend and is shown with an overline and vinculum.

Another typical parenthetical remark is this one: 813/13 = 62.(538461): However, it's likely that you may see the reptend marked with an ellipsis in daily use: 813 / 13 = 62.538461… .

Decimal 813 divided by 13 equals 62.538461.

In a fraction, 813 is equal to 813/13.
