Answer:
Sum of the interior angles = 1440 degrees.
Step-by-step explanation:
There are a total of 10 interior angles in the decagon. Now for all polygons the sum of all the exterior angles is 360 degrees. There are 10 exterior angles in the decagon and, since it is regular, each of them = 360/10 = 36 degrees. Each interior angle therefore measures 180 - 36 degrees and the sum of the interior angles is this value times ten.
360 / 10 = 36.
180 - 36 = 144.
10 * 144 = 1440 degrees.

Answer:
Step-by-step explenation . First you know that the amount of time she trained for the marathon is 125% of the time she trained last month. We also know that she trained 80 hours last month. And the question wants us to know how many hours she trained this month. So we do 100% =x
And 125% = 80 so we cross multiply it becomes 100 X 80 =125x witch eaquals to 8,000 divided by 125 witch is 64. So the final Answer is 64 . IF I AM CORRECT PLEASE MARK BRAINLIEST.
Answer:
Below.
Step-by-step explanation:
81 - x^4 Treat as the difference of 2 squares:
= (9 - x^2)(9 + x^2)
We can further factor the 9 - x^2 (difference of 2 squares)
= (3 - x)(3 + x)(9 + x^2).
9 + x^2 can't be factored.
