Jambmaths question:
How many sides has regular polygon whose interior angle is 135o each
Option A:
9
Option B:
8
Option C:
12
Option D:
10
Jamb Maths Solution:
Each exterior angle = 180o – 135o = 45o
Total sum of exterior angle of any polygon is 360o
The number of sides will be
${{45}^{\circ }}n={{360}^{\circ }},\text{ }n=8$
The number of sizes of the polygon is 8
