Each side of a regular convex polygon subtends an angle of 30° at its center. Calculate each interior angle

A.
75^{o} 
B.
150^{o} 
C.
160^{o} 
D.
68^{o}
Correct Answer: Option B
Explanation
Interior angle = 2(75°)
= 150°
Each side of a regular convex polygon subtends an angle of 30° at its center. Calculate each interior angle
Interior angle = 2(75°)
= 150°
