s = ( n - 2 ) (180°)
A. 1260°
B. 720°
C. 1620°
D. 1080°

Correct answer will be rewarded with full points as well as the mark of the brainliest

Answer 1

The sum s for n=8 is
.. s = (8 -2)(180°)
.. s = 1080°

Selection D is appropriate.

_____
Put the number into the formula where the corresponding variable is, then do the arithmetic. A calculator can do the arithmetic for you, if necessary.

Answer 2

S= (8-2) (180°)= (8-2)=6×180=1080 the answer is D.
