Answer:
Remember that regular octagon is a figure with eight sides, where all of them are equal. The image attached shows a regular octagon.
So, if we want to map the octagon on to itself using rotation, we need to rotate 90° clockwise, or make to moves of 45° each, that way the octagon would be as the original one because it has equal sides.
When you rotate the first 45°, you would have like an inclined octagon, so you need to rotate another 45° to get the same octagon as the original.
So, the minimum degree would be 45°, doing it twice.
-14 = 4a
Answer:
a = -3 1/2
Step-by-step explanation:
To solve the equation for a, divide each side by 4.
-14 = 4a
-14/4 = 4a/4
-14/4 = a
Simplify the fraction by dividing the top and bottom by 2.
-7/2 =a
This is an improper fraction, so change to a mixed number.
2 goes into 7 3 times with 1 left over.
-7/2 = -3 1/2
a = -3 1/2
-14=4a
