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°
The value of 3 is thousandth
Answer: 10
Step-by-step explanation:
Any number in between absolute value bars is always going to be positive. So it becomes:
1 + 9 = 10
Answer:
z = (1 + i)6 =³√2(cos π4+ isinπ4)´6= 8 µcos3π2+ isin3π2)¶= −8i. Hence |z| = 8 and ¯z = 8i. z = (1 + i)
