What is the sum of the measures of the interior angles of a 7-sided polygon?
1 answer:
Answer: 900
Step-by-step explanation: To answer this question it has to be assumed that it is a regular polygon ie with equal angles.
Sum of the interior angles = (7-2)*180 = 5*180 = 900 degrees
So each interior angle = 900/7 = 128.57 degrees.

Hello :
incorrect answer because :
![\sqrt{ a^{2} + b^{2} } \neq \sqrt{ a^{2} } + \sqrt{ b^{2}} \neq a+b](https://tex.z-dn.net/?f=%20%5Csqrt%7B%20a%5E%7B2%7D%20%2B%20b%5E%7B2%7D%20%7D%20%20%5Cneq%20%20%20%5Csqrt%7B%20a%5E%7B2%7D%20%7D%20%2B%20%5Csqrt%7B%20b%5E%7B2%7D%7D%20%20%5Cneq%20a%2Bb)
but :
![\sqrt{ (a+b)^{2} } = a+b](https://tex.z-dn.net/?f=%20%5Csqrt%7B%20%28a%2Bb%29%5E%7B2%7D%20%7D%20%3D%20a%2Bb)
