Answer: In geometry, a decagon (from the Greek δέκα déka and γωνία gonía, "ten angles") is a ten-sided polygon or 10-gon. The total sum of the interior angles of a simple decagon is 1440°.
Answer:
8.84 x 10^3
Step-by-step explanation:
first, you need to turn the digits in 8840 so it is lower than 10 and at least 1
so 8840 ÷ 1000 gives us 8.840, or 8.84
Then, we need to add the multiplication that makes the original number
8.84 x 1000 = 8840
We simplify this by counting the factors zeros
1 0 0 0 = 3 zeros
Finally, but the amount of zeros in the exponent
8.84 x 10^3
