Step-by-step explanation:
Solution
Interesting question.
The formula for the sum of the interior angles is
(n - 2)*180 = x
In this case, x = 1260
(n - 2)*180 = 1260 Divide both sides by 180
(n -2 )* 180/180 = 1260/180
( n - 2) = 7 Remove the brackets
n - 2 = 7 Add 2 to both sides
n - 2 + 2 = 7 +2 The 2s on the left cancel
n = 9
