Answer:
Option 1) 10 sides
Step-by-step explanation:
We are given a regular polygon. The sum of interior angles measure upto 1440 degrees.
Since it is a regular polygon, it satisfies the following properties:
- All the sides are equal.
- All interior angle have same measure.
Let the regular polygon have n sides.
Then, the sum of interior angle is given by:
![(n-2)\times 180^\circ](https://tex.z-dn.net/?f=%28n-2%29%5Ctimes%20180%5E%5Ccirc)
Putting the values, we get,
![(n-2)\times 180 = 1440\\\\n-2 = \dfrac{1440}{180}\\\\n-2 = 8\\n = 8 + 2\\n =10](https://tex.z-dn.net/?f=%28n-2%29%5Ctimes%20180%20%3D%201440%5C%5C%5C%5Cn-2%20%3D%20%5Cdfrac%7B1440%7D%7B180%7D%5C%5C%5C%5Cn-2%20%3D%208%5C%5Cn%20%3D%208%20%2B%202%5C%5Cn%20%3D10)
Thus, there are 10 sides. The regular polygon is a regular decagon.
Answer:
s= -5
Step-by-step explanation:
-50=10s
divide both by 10
-5=s
Answer: 10
Step-by-step explanation:
8^2=64
