Dot Product = 0
Answer:
Step-by-step explanation:
Sum of interior angle of any polygon =(n-2) × 180°where n represents the number of sides in any polygon.
Or 1260 =(n-2)x180
Dividing both sides by 180:
7=n-2
Adding both sides by 2 we have :
n=9.
Hence a nanogon will have the sum of interior angles as 1260°.
Answer:
it is false because, in the equation 84 does not equal 84.
Step-by-step explanation:
Hope I could help, if you need the equation let me know! :)
so, what we do is, we multiply the value by a power of 10, that moves the recurring numbers to the left of the dot, in this case we want moved the "15", so we'll need two zeros, so we'll be using 100.
