Each exterior angle of a polygon is 30o. Calculate the sum of the interior angles
A
540o
B
720o
C
1080o
D
1800o
Verified Correct Answer: D.
Step-by-Step Mathematical Solution
number of sides = \(\frac{360^o}{\theta} = \frac{360^o}{306o}\)
n = 12o
Sum of interior angle = (n - 2) 180o
(12 - 2) 180v = 10 x 180o
= 1800o
