Question 47

If the interior angle of a polygon is 108°, then it is a

Solution

Share

Interior angle = 108$$^{\circ\ }$$

Then , exterior angle = 180 - 108 = 72$$^{\circ\ }$$

Sum of exterior angle of polygon is 360$$^{\circ\ }$$

Number of sides = $$\frac{360}{72}=5$$

So, the polygon is pentagon.
